Know more about the Cloudera Manager 7.11.3 cumulative hotfixes 10.

This cumulative hotfix was released on November 12, 2024.

New features and changed behavior for Cloudera Manager 7.11.3 CHF 10 (version: 7.11.3.26-58725444):
Enhancements to the Observability page
The following changes have been made to the Observability page::
  • Added role-specific metrics to the Status and Charts Library tabs for component servers such as Pipelines, ADB, and SDX.
  • Added relevant metrics across all Observability component servers to the Status and Charts Library tabs for the Observability page.
Following are the list of known issues and their corresponding workarounds that are shipped for Cloudera Manager 7.11.3 CHF 10 (version: 7.11.3.26-58725444):
OPSAPS-68340: Zeppelin paragraph execution fails with the User not allowed to impersonate error.

Starting from Cloudera Manager 7.11.3, Cloudera Manager auto-configures the livy_admin_users configuration when Livy is run for the first time. If you add Zeppelin or Knox services later to the existing cluster and do not manually update the service user, the User not allowed to impersonate error is displayed.

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.

OPSAPS-69847:Replication policies might fail if source and target use different Kerberos encryption types

Replication policies might fail if the source and target Cloudera Manager instances use different encryption types in Kerberos because of different Java versions. For example, the Java 11 and higher versions might use the aes256-cts encryption type, and the versions lower than Java 11 might use the rc4-hmac encryption type.

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.

OPSAPS-69342: Access issues identified in MariaDB 10.6 were causing discrepancies in High Availability (HA) mode

MariaDB 10.6, by default, includes the property require_secure_transport=ON in the configuration file (/etc/my.cnf), which is absent in MariaDB 10.4. This setting prohibits non-TLS connections, leading to access issues. This problem is observed in High Availability (HA) mode, where certain operations may not be using the same connection.

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.

OPSAPS-70771: Running Ozone replication policy does not show performance reports
During an Ozone replication policy run, the A server error has occurred. See Cloudera Manager server log for details error message appears when you click:
  • Performance Reports > OZONE Performance Summary or Performance Reports > OZONE Performance Full on the Replication Policies page.
  • Download CSV on the Replication History page to download any report.
None
OPSAPS-70704: Kerberos connectivity check does not work as expected with JDK17 when you add Cloudera Manager peers
When you add a source Cloudera Manager that supports JDK17, the Kerberos connectivity check fails and the Error while reading /etc/krb5.conf on <hostname ; for all hosts>... error message appears.
None
OPSAPS-70713: Error appears when running Atlas replication policy if source or target clusters use Dell EMC Isilon storage
You cannot create an Atlas replication policy between clusters if one or both the clusters use Dell EMC Isilon storage.
None
OPSAPS-70297: Optional 'Run As User' for HBase initial snapshot export process
If you configure an IDBroker-based external account on the source CDP Private Cloud Base cluster and want to use it in an HBase replication policy in CDP Public Cloud Replication Manager, you must map the hbase user to the IAM role that has access to the target S3 bucket using the source Cloudera Manager > Clusters > Knox service > Instances > Kerberos Proxy Block property. Also, you can replicate HBase data using that replication policy to only one target COD cluster.
None
CDPD-53185: Clear REPL_TXN_MAP table on target cluster when deleting a Hive ACID replication policy
The entry in REPL_TXN_MAP table on the target cluster is retained when the following conditions are true:
  1. A Hive ACID replication policy is replicating a transaction that requires multiple replication cycles to complete.
  2. The replication policy and databases used in it get deleted on the source and target cluster even before the transaction is completely replicated.

In this scenario, if you create a database using the same name as the deleted database on the source cluster, and then use the same name for the new Hive ACID replication policy to replicate the database, the replicated database on the target cluster is tagged as ‘database incompatible’. This happens after the housekeeper thread process (that runs every 11 days for an entry) deletes the retained entry.

Create another Hive ACID replication policy with a different name for the new database.
OPSAPS-71592: Replication Manager does not read the default value of “ozone_replication_core_site_safety_valve” during Ozone replication policy run
During the Ozone replication policy run, Replication Manager does not read the value in the ozone_replication_core_site_safety_valve advanced configuration snippet if it is configured with the default value.
To mitigate this issue, you can use one of the following methods:
  • 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.
Following are the list of fixed issues that were shipped for Cloudera Manager 7.11.3 CHF 10 (version: 7.11.3.26-58725444):
OPSAPS-71666: Replication Manager uses the required property values in the “ozone_replication_core_site_safety_valve ” in the source Cloudera Manager during Ozone replication policy run
During an Ozone replication policy run, Replication Manager obtains the required properties and its values from the ozone_replication_core_site_safety_valve. It then adds the new properties and its values and overrides the value for existing properties in the core-site.xml file. Replication Manager uses this file during the Ozone replication policy run.
OPSAPS-71647: Ozone replication fails for incompatible source and target Cloudera Manager versions during the payload serialization operation
Replication Manager now recognizes and annotates the required fields during the payload serialization operation. For the list of unsupported Cloudera Manager versions that do not have this fix, see Preparing clusters to replicate Ozone data.
OPSAPS-71615: Service monitor crashes due to an out-of-memory (OOM) error.
This issue is fixed now.
OPSAPS-71258: Kafka, SRM, and SMM cannot process messages compressed with Zstd or Snappy
Kafka, SRM, and SMM cannot process messages compressed with Zstd or Snappy if the /tmp directory is mounted with noexec flag. This issue is fixed now.
OPSAPS-70848: Hive external table replication policies succeed when the source cluster uses Dell EMC Isilon storage
During the Hive external table replication policy run, the replication policy failed at the Hive Replication Export step. This issue is resolved.
OPSAPS-70822: Save the Hive external table replication policy on the ‘Edit Hive External Table Replication Policy’ window
Replication Manager saves the changes as expected when you click Save Policy after you edit a Hive replication policy. To edit a replication policy, you click Actions > Edit Configuration for the replication policy on the Replication Policies page.
OPSAPS-69782: Exception appears if the peer Cloudera Manager's API version is higher than the local cluster's API version
HBase replication using HBase replication policies in CDP Public Cloud Replication Manager between two Data Hubs/COD clusters succeed as expected when all the following conditions are true:
  • The destination Data Hub/COD cluster’s Cloudera Manager version is 7.9.0-h7 through 7.9.0-h9 or 7.11.0-h2 through 7.11.0-h4, or 7.12.0.0.
  • The source Data Hub/COD cluster's Cloudera Manager major version is higher than the destination cluster's Cloudera Manager major version.
  • The Initial Snapshot option is chosen during the HBase replication policy creation process and/or the source cluster is already participating in another HBase replication setup as a source or destination with a third cluster.
OPSAPS-66459: Enable concurrent Hive external table replication policies with the same cloud root
When the HIVE_ALLOW_CONCURRENT_REPLICATION_WITH_SAME_CLOUD_ROOT_PATH feature flag is enabled, Replication Manager can run two or more Hive external table replication policies with the same cloud root path concurrently.

For example, if two Hive external table replication policies have s3a://bucket/hive/data as the cloud root path and the feature flag is enabled, Replication manager runs these policies concurrently.

By default, this feature flag is disabled. To enable the feature flag, contact your Cloudera account team.
