Following are the list of known issues and their corresponding workarounds that are shipped for Cloudera Manager 7.7.1 CHF12 (version: 7.7.1-h12-43414392):

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.

On the Cloudera Manager UI, navigate to the HDFS service, by clicking on the HDFS service under the Cluster.
Click the Configuration tab. Search for the HDFS Client Advanced Configuration Snippet (Safety Valve) for hdfs-site.xml configuration parameter.
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
Then click the Save Changes button to save the safety valve entry.
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 CHF12 (version: 7.7.1-h12-43414392):

OPSAPS-64882: Upgraded PostgreSQL version: The PostgreSQL version is upgraded from 42.2.24.jre7 to 42.5.1 version to fix CVE issues.
OPSAPS-65831: DistCp job deletes multiple threads for bootstrap replication: Performance of bootstrap or FFL (full file listing) replication for destination-side delete of paths missing from the source is improved with the following optional behaviors.; FFL replication schedules all the missing paths for deletion regardless of parent relationships. When the com.cloudera.enterprise.distcp.parent-only-delete.enabled safety valve is set to "true", only the topmost deleted paths are scheduled for deletions and their descendants or children cannot be accessed. This is optional and by default turned off (which preserves the previous behavior).

Delete requests can be issued from multiple threads concurrently to improve performance, and can be enabled and configured using the following safety valves:

com.cloudera.enterprise.distcp.parallel-ffl-delete.enabled. Default is "false".

com.cloudera.enterprise.distcp.parallel-ffl-delete.threads. Default is 20.

com.cloudera.enterprise.distcp.parallel-ffl-delete.max-queue-size. Default is 10000.
