Cloudera Manager 7.13.1.200 Cumulative hotfix 2

In case your OS is either RHEL 9 or SLES 15 or Ubuntu 2004 or Ubuntu 2204 and if you install the Cloudera Manager 7.13.1.x version, then create a symbolic link using root user privileges on the node that host the Service Monitor service (cloudera-scm-firehose) at /opt/cloudera/cm/lib/cdh71/cdh71-hive-client-7.13.1-shaded.jar, pointing to /opt/cloudera/cm/lib/cdh7/cdh7-hive-client-7.13.1-shaded.jar.

Restart the Service Monitor service post the change. This will allow the Service Monitor to perform Canary testing correctly on the HMS (Hive Metastore) service.

Once done, restart the Cloudera Manager server(s) for the updated configuration to be picked.

To resolve this issue temporarily, you must perform the following steps:

• Upgrade the target Cloudera Manager before you upgrade the source Cloudera Manager for 7.11.3 CHF12 version only.
• Pause all replication policies, upgrade source Cloudera Manager, upgrade destination Cloudera Manager, and unpause the replication policies.
• Upgrade source Cloudera Manager, upgrade target Cloudera Manager, and rerun the failed Ozone replication policies between the source and target clusters.

If you add Zeppelin or Knox services later to the existing cluster, you must manually add the respective service user to the livy_admin_users configuration in the Livy configuration page.

Ensure that both the instances use the same Java version. If it is not possible to have the same Java versions on both the instances, ensure that they use the same encryption type for Kerberos. To check the encryption type in Cloudera Manager, search for krb_enc_types on the Cloudera Manager > Administration > Settings page.

To resolve the issue temporarily, you can either comment out or disable the line require_secure_transport in the configuration file located at /etc/my.cnf.

• Remove some or all the properties in ozone_replication_core_site_safety_valve, and move them to ozone-conf/ozone-site.xml_service_safety_valve.
• Add a dummy property with no value in ozone_replication_core_site_safety_valve. For example, add <property><name>dummy_property</name><value></value></property>, save the changes, and run the Ozone replication policy.

1. In the Cloudera Manager, go to Hive > Configuration
2. Add the value for hive.compactor.initiator.on to true in the "Hive Service Advanced Configuration Snippet (Safety Valve) for hive-site.xml"
3. Save the changes and Restart.

• Log in to the Ranger Admin host(s) on the source cluster.
• Identify the Cloudera Manager agent PEM file using the # cat /etc/cloudera-scm-agent/config.ini | grep -i client_cert_file command. For example, the file might reside in client_cert_file=/myTLSpath/cm_server-cert.pem location.
• Create the path for the new PEM file using the # mkdir -p /var/lib/cloudera-scm-agent/agent-cert/ command.
• Copy the client_cert_file from config.ini as cm-auto-global_cacerts.pem file using the # cp /myTLSpath/cm_server-cert.pem /var/lib/cloudera-scm-agent/agent-cert/cm-auto-global_cacerts.pem command.
• Change the ownership to 644 using the # chmod 644 /var/lib/cloudera-scm-agent/agent-cert/cm-auto-global_cacerts.pem command.

• Resume the Ranger replication policy in Replication Manager.

Additionally, you must ensure that you do not update the property values in Ozone Replication Advanced Configuration Snippet (Safety Valve) for core-site.xml for Ozone replication jobs. This is because the values in this advanced configuration snippet overrides the property values in core-site.xml and not the ozone-site.xml file.

Different property values in Ozone Service Advanced Configuration Snippet (Safety Valve) for ozone-conf/ozone-site.xml and Ozone Replication Advanced Configuration Snippet (Safety Valve) for core-site.xml result in a nondeterministic behavior where the replication job picks up either value during the job run which leads to incorrect results or replication job failure.

1. SSH to the host on which the Ranger Admin role is running.
2. Find the ranger-replication.sh file.
3. Create a backup copy of the file.
4. Locate substituteEnv SOURCE_DESTINATION_RANGER_SERVICE_NAME_MAPPING ${RANGER_REPL_SERVICE_NAME_MAPPING} in the file.
5. Modify it to substituteEnv SOURCE_DESTINATION_RANGER_SERVICE_NAME_MAPPING "'${RANGER_REPL_SERVICE_NAME_MAPPING//\"}'"
6. Save the file.
7. Rerun the Ranger replication policy.

• Use different bucket names on the source and target clusters.
• Set the fs.s3a.delegation.token.binding property to an empty value in ozone_replication_core_site_safety_valve to disable the delegation tokens for Ozone replication policy jobs.

1. In Cloudera Manager, go to SMM > Configuration > Streams Messaging Manager Rest Admin Server Advanced Configuration Snippet (Safety Valve)
2. Override bootstrap server URL (hostname:port as set in the listeners for broker) for streams-messaging-manager.yaml.
3. Save your changes.
4. Restart SMM.

1. Access the Ranger Console (Ranger Admin web UI).
2. Click the cm_atlas resource-based service.
3. Add the schemaregistry user to the all - * policies.
4. Click Manage Service > Edit Service.
5. Add the schemaregistry user to the default.policy.users property.
