    Due to a security vulnerability, a Cloudera Manager read-only user can access sensitive cluster information. Products affected: Cloudera Manager Releases affected:. Cloudera Manager 5.12 and all prior releases. Cloudera Manager 5.13.0, 5.13.1, 5.13.2, 5.13.3. Cloudera Manager 5.14.0, 5.14.1, 5.14.2, 5.14.3.

    Cloudera Manager 5.15.0 Users affected: All Date of detection: April 18th, 2018 Detected by: Cloudera Severity: High Impact: Sensitive Information Disclosure CVE: CVE-2018-10815 Immediate action required: Upgrade Cloudera Manager to a release with the fix. Addressed in release/refresh/patch: Cloudera Manager 5.14.4 Knowledge base: For the latest update on this issue, see the corresponding Knowledge article: TSB 2018-306: Cloudera Manager Information Disclosure Cloudera Manager should not omit LDAP GROUPMAPPING passwords from NodeManager. After upgrading Cloudera Manager, clusters on CDH 5.5 or higher will be marked as stale if they had set a value for the Hadoop User Group Mapping LDAP TLS/SSL Truststore Password or Hadoop User Group Mapping LDAP Bind User Password configuration properties. Workaround: Restart the stale services to pick up this fix. The configurations that will be marked stale are: hadoop.security.group.mapping.ldap.ssl.keystore.password, hadoop.security.group.mapping.ldap.bind.password.

    Products affected: Cloudera Manager Affected versions: Cloudera Manager 5.5 or higher Cloudera Bug: OPSAPS-45440 Import step in Hive replication can fail in 5.15.0 due to a Hive concurrency issue. In Cloudera Manager 5.15.0, BDR uses multi-threaded import and export for Hive replication by default. Because of a known Hive concurrency issue, the import step may occasionally fail with a NullPointerException for either the add partition or create table operations. Workaround: Most of the time, running the replication again will be successful. If you continue to run into this issue, you can disable multi-threaded import and export by setting the Number of concurrent HMS connections on the Advanced tab of the replication schedule to 0 or fewer. Jane kya chahe man bawra mp3 song free download. Products affected: Cloudera Manager Affected versions: Cloudera Manager 5.15.0 Cloudera Bug: CDH-67557 Hard Restart of Cloudera Manager Agents May Cause Subsequent Service Errors.

    If a “hard restart” or “hard stop” operation is performed on a Cloudera Manager Agent, the restarted agent will erroneously restart roles that existed prior to the restart and, subsequently, 60 days later, these roles may experience errors or be killed. Products affected: Cloudera Manager Releases affected: All versions of Cloudera Manager 5.x Cloudera Bug: OPSAPS-43550, TSB-308 Knowledge base: For the latest update on this issue, see the corresponding Knowledge article: TSB 2018-308: Hard Restart of Cloudera Manager Agents May Cause Subsequent Service Errors Editing Cloudera Manager configurations in Google Chrome may lead to unexpected configuration loss. Google Chrome version 66, released on 28 April 2018, introduced behavior changes that can trigger unintended modification of existing configuration values in Cloudera Manager. If a page contains a password field, the browser aggressively applies auto-complete form data to the first text field and first password form fields. These unintended changes to the fields could be accidentally submitted unless the user pays careful attention to the visual cues (auto-filled fields that are highlighted) or change summary view presented just before submitting the changes. Products affected: Cloudera Manager Releases affected: All releases of Cloudera Manager For the latest update on this issue see the corresponding Knowledge article:. Impala Dynamic Resource Pools wrongly gives everyone access to root pool (and all child pools).

    Releases affected:. Cloudera Manager releases lower than 5.12. Cloudera Manager 5.12.0, 5.12.1, 5.12.2. Cloudera Manager 5.13.0, 5.13.1. Cloudera Manager 5.14.0, 5.14.1 Users roles affected: Cluster Administrator, Full Administrator Date of detection: January 19, 2018 Detected by: Shafeeque Olassery Kunnikkal of Ingram Micro Asia Ltd, Security Consulting & Services Severity (Low/Medium/High): High Impact: A cross-site scripting vulnerability can be used by an attacker to perform malicious actions.

    One probable form of attack is to steal the credentials of a victim’s Cloudera Manager account. CVE: CVE-2018-5798 Immediate action required: Upgrade to a release in which this issue has been fixed. Addressed in release/refresh/patch.

    Hive replication jobs can fail intermittently during the first step of replication while exporting Hive metadata. When this happens, the following message displays in Cloudera Manager: The remote command failed with error message: Hive Replication Export Step failed. The likelihood that this error can occur increases with the length of time it takes to export Hive metadata.

    If you have a very large Hive deployment (those containing many tables and partitions), and/or environments in which the Hive metastore server is under-resourced, you are more likely to see this issue. However, having many tables and partitions or having an under-resourced Hive metastore server do not cause this issue. The problem is caused by a bug and the only solution is to upgrade to a later release. Cloudera strongly recommends upgrading to anyone running Hive Replication and using Cloudera Manager 5.13.0 or 5.13.1 versions. Affected Products: Cloudera Manager Affected Versions: Cloudera Manager 5.13.0, 5.13.1 Who is Affected: Anyone using Hive Replication Severity (Low/Medium/High): High Cause and Impact: A file is created during the Hive Export Phase, and is used by later phases, such as the Transfer/Import phases. Because of a bug, sometimes the file is overwritten by another process.

    Hive Replication can thus fail intermittently because of FileNotFoundExceptions. A retry may or may not resolve the issue. This issue can potentially affect some or all Hive replication schedules. Workaround: Upgrade to Cloudera Manager 5.13.2, 5.14.1, or higher versions Addressed in release/refresh/patch: Cloudera Manager 5.13.2, 5.14.1, or higher versions. For the latest updates on this issue, see the following corresponding Knowledge Base article: HDFS DataNode stale configuration. After upgrading to Cloudera Manager 5.10 or higher, the following configuration for HDFS DataNodes will be marked as stale: dfs.datanode.balance.max.concurrent.moves. The staleness is caused by the following new feature: HDFS balancer can now be configured to specify which hosts are included and excluded or which hosts are used as sources for transferring replicas.

    Additional properties for tuning the performance of the balancer can now also be configured starting with CDH 5.10.0. Workaround: You can safely ignore this warning and defer restarting. Affected versions: Cloudera Manager 5.10.0 and higher Fixed versions: N/A Cloudera Bug: OPSAPS-36642 YARN MapReduce Job History stale configuration. When using Cloudera Manager for cross-cluster replication of HDFS and Hive, unnecessary warning logs are printed during the initial phase of replication (‘copy listing’). These logs are printed for each and every file that Cloudera Backup and Disaster Recovery (BDR) copies. This causes a very verbose log output which slows down this phase of the replication job and can affect overall replication times considerably. This happens only when both source and target clusters are running Cloudera Manager 5.14.0.

    Workaround: Upgrade to Cloudera Manager 5.14.1 (or higher), or:. In the Cloudera Manager Admin Console for the source cluster, go to the HDFS service and click Configuration HDFS Replication Environment Advanced Configuration Snippet (Safety Valve). Add the following parameter to the configuration snippet: HADOOPROOTLOGGER=ERROR.

    Save the Configuration. Warning: With this change, the amount of logging available for replication jobs will be significantly reduced, which can make it difficult to debug any issues with BDR replication. We highly recommend you revert this configuration change after upgrading to a version that includes the fix (5.14.1 or higher). Affected versions: Cloudera Manager 5.14.0 Fixed version: Cloudera Manager 5.15.0, Cloudera Manager 5.14.1 Cloudera bug: OPSAPS-44160 See TSB-289. Cloudera Manager upgrade workflow incorrectly requires deploying some optional management roles.

    Workaround:. When prompted to add Navigator and Reports Manager roles, click the main Cloudera Manager Logo to exit the wizard. Note that this action skips over a review of the Java heap size of the Host Monitor and Service Monitor roles. (Normally, Cloudera Manager recommends a value if it finds the existing values to be too small for the number of nodes being managed). If configured properly, this is not a concern.

    For more information on resource requirements for Cloudera Manager, see:. To complete the upgrade, start (or restart) the Cloudera Management Service (not the Cloudera Manager server). From the Cloudera Manager Status page, click the drop-down list next to Cloudera Management Service and select Start or Restart. Alternatively, when prompted to add the Navigator and Reports Manager roles, users can:.

    Add the Navigator Metadata Server role and click Continue. Configure a database for the Navigator Metadata Server and click Continue. Stop and Delete the Navigator Metadata Server role from the Cloudera Management Service Instances page immediately afterwards. Affected Versions: Cloudera Manager 5.14.0 Fixed version: Cloudera Manager 5.14.1, 5.15.0 Cloudera Bug: OPSAPS-44629 See TSB-290 ADLS Credentials in Log Files. When you use Cloudera Manager to configure the ADLS Connector service using the Less Secure option for the Credentials Protection Policy, it is possible for Hive audit logs to include Microsoft Azure credentials. If you are using Navigator Audit Server, these credentials may appear in audit reports.

    To mitigate this problem, make sure that access to Hive logs is appropriately controlled and that Navigator users with Auditing Viewer roles are cleared to have access to the Hive credentials. Affected Versions: Cloudera Manager 5.14.x Cloudera Bug: CDH-56241 Installing Cloudera Manager on SLES 12 Using the Installer Does Not Work.

    Navigator is not able to uniquely identify more than one cluster in installations of Cloudera Manager that support multiple clusters. This problem only occurs for Cloudera Manager deployments of version 5.12.0, 5.12.1, or 5.13.0. Avoid multi-cluster installations with these releases if you expect to use Cloudera Navigator. This problem does not affect single cluster deployments or Altus clusters. Fixed in versions: Cloudera Manager 5.14.0 (Cloudera Navigator 2.13.0), 5.13.1 (2.12.1), 5.12.2 (2.11.2) Cloudera Bug: NAV-5615 Backup and Disaster Recovery Hive replication fails intermittently. If the /user or /user/hdfs directory is encrypted, then Hive replication fails with the following message: User:hdfs not allowed to do 'DECRYPTEEK' on some-key-name. Workaround: Configure a directory to store transient data during Hive replication:.

    Open the Cloudera Manager Admin Console. Click Backup Replication Schedules. Select the replication schedule that fails and click Actions Edit Configuration. On the Advanced tab, specify an unencrypted directory for the Export Path or Directory for metadata file field. The field name depends on your Cloudera Manager version.

    Affected versions: Cloudera Manager 5.13, 5.12.x, 5.11.x, 5.10.x, 5.9.x, 5.8.x Cloudera bug: OPSAPS-43108 Backup and Disaster Recovery replication fails if the previous run is aborted. BDR replication fails if the user directory of the user specified in the Run as Peer User or Run as username field in the replication schedule is encrypted due to a change in how replications are performed. If no Run as Peer User is configured, then replication fails if the hdfs user directory is encrypted. For example, Hive replication fails on clusters where the /user/testuser directory is encrypted and the Run as username field specifies the 'testuser' user. Affected versions: Cloudera Manager 5.13.0, 5.12.x Fixed in: Cloudera Manager 5.14.0, 5.13.1. Install the Custom Service Descriptor (CSD) file.

    See. Note: Spark 2.2 requires that JDK 1.8 be deployed throughout the cluster. JDK 1.7 is not supported for Spark 2.2. Download, distribute, and activate the Parcel for the version of Spark that you are installing:.

    Spark 2.1 release 2: The parcel name includes 'cloudera2' in its name. Spark 2.2 release 1: The parcel name includes 'cloudera1' in its name. Affected versions: CDH 5.13.0 and higher Cloudera bug: CDH-56775 Record Service no longer supported as of CDH 5.13; upgrade fails after from some lower versions. After upgrading Cloudera Manager, the Hue Load Balancer and Server roles will be marked as having a stale configuration if all of these are true:. The Enable TLS/SSL for Hue property is set to true. The Hue load balancer is enabled Workaround: If your cluster uses Apache httpd 2.4 as the Hue load balancer, restart the Hue service promptly.

    If your cluster uses an earlier version of httpd, there is no urgency to restart the Hue service. (Apache httpd 2.4 is installed automatically by some recent versions of Linux, or may have been explicitly installed.) Cloudera bug: OPSAPS-40700, OPSAPS-41850 Hue Load Balancer SSL Handshake error.

    Fixed an issue with the SSL handshake in Hue when Apache httpd 2.4 or higher is used as the load balancer. The Hue load balancer previously set the ProxyPreserveHost directive to On, when it should have been set to Off. This causes problems making SSL connections when using Apache httpd 2.4 or higher. The error caused problems when verifying the CN, which older versions of Apache httpd did not encounter because they did not properly verify the CN.

    When upgrading Cloudera Manager, the Hue load balancer may be marked as having a stale configuration. If you are experiencing issues connecting to Hue with SSL, restart the Hue service to update the configuration. Cloudera bug: OPSAPS-40700 Apache MapReduce Jobs May Fail During Rolling Upgrade to CDH 5.11.0 or CDH 5.11.1. In CDH 5.11, Cloudera introduced four new counters that are reported by MapReduce jobs.

    During a rolling upgrade from a cluster running CDH 5.10.x or lower to CDH 5.11.0 or CDH5.11.1, a MapReduce job with an application master running on a host running CDH 5.10.x or lower may launch a map or reduce task on one of the newly-upgraded CDH 5.11.0 or CDH 5.11.1 hosts. The new task will attempt to report the new counter values, which the old application master will not understand, causing an error in the logs similar to the following: 2017-06-08 17:43:37,173 WARN Socket Reader #1 for port 41187 org.apache.hadoop.ipc.Server: Unable to read call parameters for client 10.17.242.22on connection protocol org.apache.hadoop.mapred.TaskUmbilicalProtocol for rpcKind RPCWRITABLE java.lang.ArrayIndexOutOfBoundsException: 23.

    This error could cause the task and the job to fail. Workaround: Avoid performing a rolling upgrade to CDH 5.11.0 or CDH 5.11.1 from CDH 5.10.x or lower.

    Instead, skip CDH 5.11.0 and CDH 5.11.1 if you are performing a rolling upgrade, and upgrade to CDH 5.12 or higher, or CDH 5.11.2 or higher when the release becomes available. Cloudera bug: DOCS-2384, TSB-241 Rolling Upgrade with GPL Extras Parcel Causes Oozie to Fail. To configure HDFS clients to automatically retry, perform the following steps:. In the Cloudera Manager web UI, select the HDFS service. Select Configuration Gateway. In the HDFS Client Advanced Configuration Snippet (Safety Valve) for hdfs-site.xml field, add the following property: dfs.client.retry.policy.enabled. Set the value to true.

    Add a description. Save the changes.

    Select Actions Deploy Client Configuration. Start the cluster. Cloudera bug: CDH-54889 hostname parameter is not passed to Impala catalog role.

    Contained a security fix for clusters using Impala with TLS (SSL) security enabled. This fix was also made in several maintenance versions of CDH that require you to upgrade Cloudera Manager. If you upgrade to a CDH version with this fix without upgrading Cloudera Manager, Impala will not function when TLS is enabled for Impala. You should upgrade Cloudera Manager first if you want to move to a CDH version with the security fix. This issue affects upgrades of Cloudera Manager and CDH to version 5.11.1.

    There are two ways you can workaround this issue. This issue affects Cloudera Manager 5.7.0 and 5.7.1 installed on RHEL 7.x or CentOS 7.x. On RHEL 7.x and CentOS 7.x systems, certain configuration actions intended to be executed only once during enablement of HDFS HA or migration of HDFS roles might be erroneously re-executed if a system shutdown or reboot occurs within next 24 hours of either operation. This can result in data loss and inconsistent state if the user has performed a NameNode format or JournalNode format, which are part of both the enablement of HDFS HA (adding a standby NameNode) and relocation (migration) of NameNodes roles to other hosts. Edits to HDFS metadata stored in JournalNodes could be lost in these situations, requiring manual repair to recover recent changes to HDFS data.

    If you experience this issue, please contact Cloudera Support for assistance. For the latest update on this issue see the corresponding Knowledge article: Resolution: Upgrade to Cloudera Manager 5.7.2 or higher immediately, and perform a hard restart of Cloudera Manager agents.

    In CM 5.11.0, the new Graceful Shutdown Timeout configuration property does not work as expected. As a result, Kafka takes an additional 30 seconds (by default) to shut down, but will still only have 30 seconds to complete its controlled shutdown, before Cloudera Manager forcibly shuts down Kafka brokers regardless of the configured timeout. Workaround: Wait longer for the shutdown to occur, or reduce the Graceful Shutdown Timeout to a very low value, for example: 1. (You should restore the original value when you upgrade to a Cloudera Manager release with the fix for this issue, although it will not cause a critical problem if left at a low value.) There is no workaround that allows you to increase the real time that Kafka has to perform shutdown until this issue is fixed. Fixed in Cloudera Manager 5.11.1. Cloudera bug: OPSAPS-40106 Spark Gateway roles should be added to every host.

    Workaround:. In Cloudera Manager, go to the Hive service.

    Click the Configuration tab. Search for the following Advanced Configuration Snippets:.

    HiveServer2 Advanced Configuration Snippet (Safety Valve) for hive-site.xml. Hive Client Advanced Configuration Snippet (Safety Valve) for hive-site.xml. Click the icon to add the following property and value to both Advanced Configuration Snippets: Name: spark.yarn.security.tokens.hbase.enabled Value: false. Click Save Changes.

    Click the stale configuration icon to restart stale services, including any dependent services. Follow the on-screen prompts.

    Click Actions Deploy Client Configuration. When you execute a query that uses a HBase-backed table, set this parameter back to true. You can do this by changing the configuration as described above (set each value to true) or by using a set command and then issuing the query. For example: set spark.yarn.security.tokens.hbase.enabled=true; SELECT.

    FROM HBASEBACKEDTABLE. Fixed in Cloudera Manager 5.8.5 and 5.9.3. Cloudera bug: OPSAPS-39021 Hive Replication fails when Impala is SSL enabled but Hadoop services are not. Workaround:. In Cloudera Manager, go to the HDFS service.

    Click the Configuration tab. Search for and enter the appropriate values for the following parameters:. Cluster-Wide Default TLS/SSL Client Truststore Location. Cluster-Wide Default TLS/SSL Client Truststore Password Impala metatdata replication is not supported, but will be supported in a later maintenance release. This support also ensures that connection to Impala is successful when SSL is enabled even if Kerberos is not enabled. Cloudera bug: OPSAPS-38700, OPSAPS-38720 Fixed in Cloudera Manager 5.11, 5.10.1, 5.9.2, 5.8.4, 5.7.6.

    Python-psycopg2 Dependency. Cloudera Manager 5.8 and higher has a new dependency on the package python-psycopg2. This package is not available in standard SLES 11 and SLES 12 repositories. You need to add this repository or install it manually to any machine that runs the Cloudera Manager Agent before you install or upgrade Cloudera Manager. If the Cloudera Manager Server and Agent run on the same host, install the Cloudera Manager Server first and then add the python-psycopg2 repository or package.

    After adding the repository or package, install the Cloudera Manager Agent. Workaround Download the python-psycopg2 repository or package from the following URL by selecting the correct SLES version:. Pauses in Cloudera Manager after adding peer. Increase the memory allocated to Cloudera Manager:. On the Cloudera Manager server host, edit the /etc/default/cloudera-scm-server file. In the Java Options section, change the value of the -Xmx argument of the CMFJAVAOPTS property from -Xmx2G to -Xmx4G.

    For example: export CMFJAVAOPTS="-Xmx4G -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp'. Restart the Cloudera Manager server: sudo service cloudera-scm-server restart Fixed in Cloudera Manager 5.11 Cloudera bug: OPSAPS-38868 Cannot select time period in custom charts in C5.9.

    Hive Replication Schedules that use Amazon S3 as the Source or Destination fail when using temporary AWS credentials. The following error displays: Message: Hive Replication Metadata Transfer Step Failed - com.cloudera.com.amazonaws.services.s3.model.AmazonS3Exception: Status Code: 403, AWS Service: Amazon S3, AWS Request ID: 76D1F6A02792908A, AWS Error Code: null, AWS Error Message: Forbidden, S3 Extended Request ID: Xy3nAS4HSPKLA6hHKvpqReBud7M1Fhk7On0HttYGE0eKPHKwiFkTPQxEVU82OZq5d8omSrdbhcI=. Cloudera bug: OPSAPS-37514 Hive table Views do not get restored from S3.

    After upgrading to 5.7 or higher, you might see a reduced Java heap maximum on Impala Catalog Server due to a change in its default value. Upgrading from Cloudera Manager lower than 5.7 to Cloudera Manager 5.8.2 no longer causes any effective change in the Impala Catalog Server Java Heap size. When upgrading from Cloudera Manager 5.7 or later to Cloudera Manager 5.8.2, if the Impala Catalog Server Java Heap Size is set at the default (4GB), it is automatically changed to either 1/4 of the physical RAM on that host, or 32GB, whichever is lower. This can result in a higher or a lower heap, which could cause additional resource contention or out of memory errors, respectively.

    Cloudera bug: OPSAPS-34039 Cloudera Manager 5.7.4 installer does not show Key Trustee KMS. In some cases, provisioning of a cluster may fail at the start of the process. This does not happen in all cases and is mainly noticed on RHEL 6 and especially when some hosts are reporting bad health. Releases affected: 5.5.0-5.5.3, 5.6.0-5.6.1, 5.7.0 Releases containing the fix: 5.5.4, 5.7.1 For releases containing the fix, parcel activation and first run command now completes as expected, even when some hosts report bad health. This issue is fixed in Cloudera Manager 5.5.4 and 5.7.1 and higher. Cloudera bug: OPSAPS-33564 Cloudera Manager can run out of memory if a remote repository URL is unreachable.

    When KDC connectivity is bad, the JVM takes 30 seconds before retrying or declaring failure to connect. Meanwhile, the JournalNode write timeout (which needs KDC authentication for the first write, or under troubled connectivity), is only 20 seconds. Workaround: In krb5.conf, set the kdctimeout parameter value to 3 seconds. In Cloudera Manager, perform the following steps:. Go to Administration Settings Kerberos.

    Add the kdctimeout parameter to the Advanced Configuration Snippet (Safety Valve) for libdefaults section of krb5.conf property. This should give the JVM enough time to try connecting to a KDC before the JournalNode timeout. The HDFS File browser in Cloudera Manager fails when HDFS federation is enabled. Sqoop 2 will not start or loses data when upgrading from Cloudera Manager 5.4.0 or 5.4.1 to Cloudera Manager 5.4.3, or when upgrading Cloudera Manager 3 or 4 to Cloudera Manager 5.4.0 or 5.4.1. This is due to Cloudera Manager erroneously configuring the Derby path with “ repositoy' instead of ' reposito ry'. To upgrade Cloudera Manager, use one of the following workarounds:. Workaround for Upgrading from Cloudera Manager 3 or 4 to Cloudera Manager 5.4.0 or 5.4.1.

    Log in to your Sqoop 2 server host using SSH and move the Derby database files to the new location, usually from /var/lib/sqoop2/reposito ry to /var/lib/sqoop2/repositoy. Start Sqoop2. If you found this problem while upgrading CDH, run the Sqoop 2 database upgrade command using the Actions drop-down menu for Sqoop 2. Workaround for Upgrading from Cloudera Manager 5.4.0 or 5.4.1 to Cloudera Manager 5.4.3. Log in to your Sqoop 2 server host using SSH and move the Derby database files to the new location, usually from /var/lib/sqoop2/repositoy to /var/lib/sqoop2/reposito ry. Start Sqoop2, or if you found this problem while upgrading CDH, run the Sqoop 2 database upgrade command using the Actions drop-down menu for Sqoop 2.

    NameNode incorrectly reports missing blocks during rolling upgrade. HiveServer2 requires a Spark on YARN gateway on the same host in order for Hive on Spark to work. You must deploy Spark client configurations whenever there's a change in order for HiveServer2 to pick up the change. CSDs that depend on Spark will get incomplete Spark client configuration.

    Note that Cloudera Manager does not ship with any such CSDs by default. Cloudera bug: OPSAPS-25695 Workaround: Use /etc/spark/conf for Spark configuration, and ensure there is a Spark on YARN gateway on that host. Solr, Oozie and HttpFS fail when KMS and TLS/SSL are enabled using self-signed certificates. When the KMS service is added and TLS/SSL is enabled, Solr, Oozie and HttpFS are not automatically configured to trust the KMS's self-signed certificate and you might see the following error.

    Org.apache.oozie.service.AuthorizationException: E0501: Could not perform authorization operation, sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target Cloudera bug: OPSAPS-23392, CDH-23460, CDH-23189 Workaround: You must explicitly load the relevant truststores with the KMS certificate to allow these services to communicate with the KMS. To do so, edit the truststore location and password for Solr, Oozie and HttpFS (found under the HDFS service) as follows. Go to the Cloudera Manager Admin Console.

    Go to the Solr/Oozie/HDFS service. Click the Configuration tab. Search for ' TLS/SSL Certificate Trust Store File' and set this property to the location of truststore file. Search for ' TLS/SSL Certificate Trust Store Password' and set this property to the password of the truststore.

    Click Save Changes to commit the changes. Cloudera Manager 5.3.1 upgrade fails if Spark standalone and Kerberos are configured. ACLs configured for the KMS (File) and KMS (Navigator Key Trustee) services do not work since these services do not receive the values for hadoop.security.group.mapping and related group mapping configuration properties. Cloudera bug: OPSAPS-24483 Workaround: KMS (File): Add all configuration properties starting with hadoop.security.group.mapping from the NameNode core-site.xml to the KMS (File) property, Key Management Server Advanced Configuration Snippet (Safety Valve) for core-site.xml KMS (Navigator Key Trustee): Add all configuration properties starting with hadoop.security.group.mapping from the NameNode core-site.xml to the KMS (Navigator Key Trustee) property, Key Management Server Proxy Advanced Configuration Snippet (Safety Valve) for core-site.xml. Exporting and importing Hue database sometimes times out after 90 seconds. Executing 'dump database' or 'load database' of Hue from Cloudera Manager returns 'command aborted because of exception: Command timed-out after 90 seconds'. The Hue database can be exported to JSON from within Cloudera Manager.

    Unfortunately, sometimes the Hue database is quite large and the export times out after 90 seconds. Cloudera bug: OPSAPS-24470 Workaround: Ignore the timeout. The command should eventually succeed even though Cloudera Manager reports that it timed out. Changing the Key Trustee Server hostname requires editing keytrustee.conf. When integrated resource management is enabled for Impala, host(s) where the Impala Llama role(s) are running must have at least one YARN role.

    This is because Llama requires the topology.py script from the YARN configuration. If this requirement is not met, you may see errors such as: 'Exception running /etc/hadoop/conf.cloudera.yarn/topology.py java.io.IOException: Cannot run program '/etc/hadoop/conf.cloudera.yarn/topology.py' in the Llama role logs, and Impala queries may fail. Cloudera bug: OPSAPS-23728 Workaround: Add a YARN gateway role to each Llama host that does not already have at least one YARN role (of any type). The high availability wizard does not verify that there is a running ZooKeeper service.

    Cloudera Manager log aggregation and search features are incompatible with the log formatting needed by the Accumulo Monitor. Attempting to use either the 'Log Search' diagnostics feature or the log file link off of an individual service role's summary page will result in empty search results. Cloudera bug: OPSAPS-21675 Severity: High Workaround: Operators can use the Accumulo Monitor to see recent severe log messages.

    They can see recent log messages below the WARNING level via a given role's process page and can inspect full logs on individual hosts by looking in /var/log/accumulo. Cloudera Manager incorrectly sizes Accumulo Tablet Server max heap size after 1.4.4-cdh4.5.0 to 1.6.0-cdh4.6.0 upgrade. Because the upgrade path from Accumulo 1.4.4-cdh4.5.0 to 1.6.0-cdh4.6.0 involves having both services installed simultaneously, Cloudera Manager will be under the impression that worker hosts in the cluster are oversubscribed on memory and attempt to downsize the max heap size allowed for 1.6.0-cdh4.6.0 Tablet Servers. Cloudera bug: OPSAPS-21806 Severity: High Workaround: Manually verify that the Accumulo 1.6.0-cdh4.6.0 Tablet Server max heap size is large enough for your needs.

    Cloudera recommends you set this value to the sum of 1.4.4-cdh4.5.0 Tablet Server and Logger heap sizes. Accumulo installations using LZO do not indicate dependence on the GPL Extras parcel. Accumulo 1.6 installations that use LZO compression functionality do not indicate that LZO depends on the GPL Extras parcel. When Accumulo is configured to use LZO, Cloudera Manager has no way to track that the Accumulo service now relies on the GPL Extras parcel. This prevents Cloudera Manager from warning administrators before they remove the parcel while Accumulo still requires it for proper operation. Cloudera bug: OPSAPS-21680 Workaround: Check your Accumulo 1.6 service for the configuration changes mentioned in the Cloudera documentation for using Accumulo with CDH prior to removing the GPL Extras parcel.

    If the parcel is mistakenly removed, reinstall it and restart the Accumulo 1.6 service. Created pools are not preserved when Dynamic Resource Pools page is used to configure YARN or Impala. Pools created on demand are not preserved when changes are made using the Dynamic Resource Pools page. If the Dynamic Resource Pools page is used to configure YARN or Impala services in a cluster, it is possible to specify pool placement rules that create a pool if one does not already exist.

    If changes are made to the configuration using this page, pools created as a result of such rules are not preserved across the configuration change. Cloudera bug: OPSAPS-19942 Workaround: Submit the YARN application or Impala query as before, and the pool will be created on demand once again. User should be prompted to add the AMON role when adding MapReduce to a CDH 5 cluster.

    Impala queries fail on CDH 4.1 when Hive 'Bypass Hive Metastore Server' option is selected. Workaround: Add the following to Impala catalog server advanced configuration snippet for hive-site.xml, replacing HiveMetastoreServerHost with the host name of your Hive Metastore Server: hive.metastore.local false hive.metastore.uris thrift:// HiveMetastoreServerHost:9083 Rolling Upgrade to CDH 5 is not supported.

    After collecting Diagnostic Data and using the Download Diagnostic Data button to download the created zip file to the local system, the zip file cannot be opened using the FireFox browser on a Macintosh. This is because the zip file is created as a Zip64 file, and the unzip utility included with Macs does not support Zip64. The zip utility must be version 6.0 or later. You can determine the zip version with unzip -v. Cloudera bug: OPSAPS-13850 Workaround: Update the unzip utility to a version that supports Zip64.

    After JobTracker failover, complete jobs from the previous active JobTracker are not visible. When a JobTracker failover occurs while there are running jobs, jobs are restarted by the new active JobTracker by default. For the restarted jobs the Activity Monitor will not update the following: 1) The start time of the restarted job will remain the start time of the original job.

    2) Any Map or Reduce task that had finished before the failure happened will not be updated with information about the corresponding task that was rerun by the new active JobTracker. Cloudera bug: OPSAPS-13879 Severity: Med Workaround: None. Installing on AWS, you must use private EC2 hostnames.

    When installing on an AWS instance, and adding hosts using their public names, the installation will fail when the hosts fail to heartbeat. Severity: Med Workaround: Use the Back button in the wizard to return to the original screen, where it prompts for a license. Rerun the wizard, but choose 'Use existing hosts' instead of searching for hosts.

    Now those hosts show up with their internal EC2 names. Continue through the wizard and the installation should succeed. If HDFS uses Quorum-based Storage without HA enabled, the SecondaryNameNode cannot checkpoint. If HDFS is set up in non-HA mode, but with Quorum-based storage configured, the dfs.namenode.edits.dir is automatically configured to the Quorum-based Storage URI. However, the SecondaryNameNode cannot currently read the edits from a Quorum-based Storage URI, and will be unable to do a checkpoint. Severity: Medium Workaround: Add to the NameNode's advanced configuration snippet the dfs.namenode.edits.dir property with both the value of the Quorum-based Storage URI as well as a local directory, and restart the NameNode. For example, dfs.namenode.edits.dir qjournal://jn1HostName:8485;jn2HostName:8485;jn3HostName:8485/journalhdfs1,file:///dfs/edits Changing the rack configuration may temporarily cause mis-replicated blocks to be reported.

    Workaround:. In the CDH 4 HDFS Service Configuration tab of the Cloudera Manager Admin Console, search for 'nameservice'. In the Mountpoints field, change the mount point from '/' to a list of mount points that are in the namespace that the Nameservice will manage. (You can enter this as a comma-separated list - for example, '/hbase, /tmp, /user' or by clicking the plus icon to add each mount point in its own field.) You can determine the list of mount points by running the command hadoop fs -ls / from the CLI on the NameNode host. Historical disk usage reports do not work with federated HDFS.

    The Force Overwrite option, if checked, forces overwriting data in the target metastore if there are incompatible changes detected. For example, if the target metastore was modified and a new partition was added to a table, this option would force deletion of that partition, overwriting the table with the version found on the source. If the Force Overwrite option is not set, recurring replications may fail. Severity: Med Workaround: Set the Force Overwrite option.

    Cloudera Manager set cataloged default JVM memory to 4G can cause an out of memory error during upgrade to Cloudera Manager 5.7 and higher.
