Cloudera Manager 7.7.1 Cumulative hotfix 9

Know more about the Cloudera Manager 7.7.1 cumulative hotfixes 9.

This cumulative hotfix was released on May 18, 2023.

Following are the list of known issues and their corresponding workarounds that are shipped for Cloudera Manager 7.7.1 CHF9 (version: 7.7.1-h9-40960082):
OPSAPS-68689: Unable to emit the LDAP Bind password in core-site.xml for client configurations

If the CDP cluster has LDAP group to OS group mapping enabled, then applications running in Spark or Yarn would fail to authenticate to the LDAP server when trying to use the LDAP bind account during the LDAP group search.

This is because the LDAP bind password was not passed to the /etc/hadoop/conf/core-site.xml file. This was intended behavior to prevent leaking the LDAP bind password in a clear text field.

Set the LDAP Bind password through the HDFS client configuration safety valve.
  1. On the Cloudera Manager UI, navigate to the HDFS service, by clicking on the HDFS service under the Cluster.

  2. Click the Configuration tab. Search for the HDFS Client Advanced Configuration Snippet (Safety Valve) for hdfs-site.xml configuration parameter.

  3. Add an entry with the following values:
    • Name = hadoop.security.group.mapping.ldap.bind.password
    • Value = (Enter the LDAP bind password here)
    • Description = Password for LDAP bind account

  4. Then click the Save Changes button to save the safety valve entry.

  5. Perform the instructions from the Manually Redeploying Client Configuration Files to manually deploy client configuration files to the cluster.

OPSAPS-68452: Azul Open JDK 8 and 11 are not supported with Cloudera Manager

Azul Open JDK 8 and 11 are not supported with Cloudera Manager. To use Azul Open JDK 8 or 11 for Cloudera Manager RPM/DEBs, you must manually create a symlink between the Zulu JDK installation path and the default JDK path.

After installing Azul Open JDK8 or 11, you must run the following commands on all the hosts in the cluster:
Azul Open JDK 8
RHEL or SLES
# sudo ln -s /usr/lib/jvm/java-8-zulu-openjdk-jdk /usr/lib/jvm/java-8-openjdk
Ubuntu or Debian
# sudo ln -s /usr/lib/jvm/zulu-8-amd64 /usr/lib/jvm/java-8-openjdk
Azul Open JDK 11
For DEBs only
# sudo ln -s /usr/lib/jvm/zulu-11-amd64 /usr/lib/jvm/java-11
Following are the list of fixed issues that were shipped for Cloudera Manager 7.7.1 CHF9 (version: 7.7.1-h9-40960082):
OPSAPS-67152: Cloudera Manager does not allow you to update some configuration parameters.

Cloudera Manager does not allow you to set to "0" for the dfs_access_time_precision and dfs_namenode_accesstime_precision configuration parameters.

You will not be able to update dfs_access_time_precision and dfs_namenode_accesstime_precision to "0". If you try to enter "0" in these configuration input fields, then the field gets cleared off and results in a validation error: This field is required. This issue is fixed now.

OPSAPS-59824: Set hive.hook.proto.base-directory for HMS by default

The hive.hook.proto.base-directory property, which is present for Hive on Tez (HiveServer2) was not available for the Hive metastore. Due to this, the HiveProtoEventsCleanerTask does not run and clean the old proto data.

This issue is now fixed and the hive.hook.proto.base-directory property is available in Cloudera Manager under Clusters > HIVE-1 > Configuration with a default value of /warehouse/tablespace/managed/hive/sys.db/query_data/.
