Known Issues in Cloudera Manager 7.11.3 Cumulative hotfix 7 (CDP Private Cloud Base 7.1.9 SP1)

OPSAPS-70583: File Descriptor leak from Cloudera Manager 7.11.3 CHF3 version to Cloudera Manager 7.11.3 CHF7

Unable to create NettyTransceiver due to Avro library upgrade which leads to File Descriptor leak. File Descriptor leak occurs in Cloudera Manager when a service tries to talk with Event Server over Avro.

To resolve this issue, disable the Enable Log Event Capture configuration on the Configuration page of a service.

OPSAPS-68845: Cloudera Manager Server fails to start after the Cloudera Manager upgrade

Starting from the Cloudera Manager 7.11.3 version up to the Cloudera Manager 7.11.3 CHF7 version, the Cloudera Manager Server fails to start after the Cloudera Manager upgrade due to Navigator user roles improperly handled in the upgrade in some scenarios.

None

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-69806: Collection of YARN diagnostic bundle will fail

For any combinations of CM 7.11.3 version up to CM 7.11.3 CHF7 version, with CDP 7.1.7 through CDP 7.1.8, collection of the YARN diagnostic bundle will fail, and no data transmits occur.

Upgrade to CDP 7.1.9, or downgrade to Cloudera Manager 7.7.1.

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.

CDPD-62834: Status of the deleted table is seen as ACTIVE in Atlas after the completion of navigator2atlas migration process

The status of the deleted table displays as ACTIVE.

None

CDPD-62837: During the navigator2atlas process, the hive_storagedesc is incomplete in Atlas

For the hive_storagedesc entity, some of the attributes are not getting populated.

None

OPSAPS-69897: NPE in Ozone replication from CM 7.7.1 to CM 7.11.3

When you use source Cloudera Manager 7.7.1 and target Cloudera Manager 7.11.3 for Ozone replication policies, the policies fail with Failure during PreOzoneCopyListingCheck execution: null error. This is because the target Cloudera Manager 7.11.3 does not retrieve the required source bucket information for validation from the source Cloudera Manager 7.7.1 during the PreCopyListingCheck command phase. You come across this error when you use source Cloudera Manager versions lower than 7.10.1 and target Cloudera Manager versions higher than or equal to 7.10.1 in an Ozone replication policy.

Upgrade the source Cloudera Manager to 7.11.3 or higher version.

OPSAPS-70861: HDFS replication policy creation process fails for cluster with Isilon

When you choose a source CDP Private Cloud Base cluster using the Isilon service and a target cloud storage bucket for an HDFS replication policy in CDP Private Cloud Base Replication Manager UI, the replication policy creation process fails.

Create the HDFS replication policy using Cloudera Manager REST APIs.

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-70826: Ranger replication policies fail when target cluster uses Dell EMC Isilon storage and supports JDK17

Ranger replication policies fail if the target cluster is deployed with Dell EMC Isilon storage and also supports JDK17.

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:

A Hive ACID replication policy is replicating a transaction that requires multiple replication cycles to complete.
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

DMX-3659: Updated row is replicated as inserted row

During an Iceberg replication policy run, an updated row on the source cluster is replicated as an inserted row which is incorrect. This results in a discrepancy because the number of rows for the table in the source and target clusters do not match.

None

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.

OPSAPS-71067: Wrong interval sent from the Replication Manager UI after Ozone replication policy submit or edit process.

When you edit the existing Ozone replication policies, the schedule frequency changes unexpectedly.
