Following known issues and their corresponding workarounds are shipped for Cloudera Manager 7.7.3 CHF4 (version: 7.7.3-h2-40943658):
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
OPSAPS-59723: Extra step required when using Cloudera Manager Trial installer on SLES 15 SP4
When using cloudera-manager-installer.bin to install a trial version of Cloudera Manager, the installation will fail.
Before running cloudera-manager-installer.bin, run the following command:
SUSEConnect --list-extensions
SUSEConnect -p sle-module-legacy/15.4/x86_64
zypper install libncurses5
OPSAPS-65243: Diagnostic data collection for YARN fails
Selecting Collect Diagnostic Data from the YARN > Applications page fails to generate the diagnostic data.
None
Following are the list of fixed issues that were shipped for Cloudera Manager 7.7.3 CHF4 (version: 7.7.3-h2-40943658):
OPSAPS-67130: Log4J 1.2.17 replaced with Reload4J
In this release, Cloudera has replaced all Apache Log4j 1.2.x logging libraries included with Cloudera Manager 7.7.3 Cumulative hotfix 2 with equivalent Reload4j libraries.
OPSAPS-51761: YARN task failures after upgrading to CDH 6.2.0 (Invalid arguments for cgroups resources: /var/log/hadoop-yarn/container)
Fixed an issue during upgrade in YARN, where the upgraded container-executor binary is not copied due to the container-executor file being used by running applications.
OPSAPS-65242: Alert Server Event cleanup issue
Fixed an issue where an Event Server cleanup did not work properly and now it works as intended, uses less CPU and keeps the events within the requested limits.
OPSAPS-65999: cert.py has Python 3 compatibility issues and an error occurs while performing any certificate generation and rotation operations
Fixed an issue in cert-manager code that decoded output from native OS commands. When Cloudera Manager attempts operations related to certificate generation or rotation, those operations may fail. Errors in the log file will indicate problems with string decoding. Running the cert-manager script directly from the CLI would also result in string decoding errors.
OPSAPS-66689: Hue logs get overwritten without a clear root cause
In previous implementations, multiple file handlers would write to a single log file, causing the Hue logs to be overwritten. Hue now uses a socket handler, which solves this problem.
OPSAPS-67080: Earlier, gathering Kudu diagnostic information within Cloudera Manager failed.
Now, gathering Kudu diagnostic information within Cloudera Manager no longer fails and works as expected..
