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-65706: ZooKeeper fails to restart after rollback

ZooKeeper server role fails to restart when you perform a rollback from Cloudera Manager 7.7.3 version to Cloudera Manager versions lower than 7.7.3.

The reason for ZooKeeper restart to fail is that post a rollback operation the previous version’s ZooKeeper process starts and does not allow to start ZooKeeper process after rollback (as only 1 ZooKeeper process is allowed to stay running on the host).

To restore the ZooKeeper server role to a running state, perform the below steps on all the hosts when the ZooKeeper server role fails to restart:

Run the following command to list the roles on the current host:

sudo /opt/cloudera/cm-agent/bin/supervisorctl -c /run/cloudera-scm-agent/supervisor/supervisord.conf status

Find the failing role in the above list, then run the following command to stop the role:
```
sudo /opt/cloudera/cm-agent/bin/supervisorctl -c /run/cloudera-scm-agent/supervisor/supervisord.conf
supervisor> stop 123-zookeeper-server 
supervisor> remove 123-zookeeper-server 
supervisor> exit
```
Replace the role id "123" with the appropriate number from the list in step 1.
Run the following command to terminate the Zookeeper processes by finding the PIDs:
```
sudo ps -ef | grep -i zookeeper
```

Run the following command to remove the supervisor.conf of ZooKeeper from supervisor:

rm /run/cloudera-scm-agent/supervisor/include/123-zookeeper-server.conf
sudo kill -9 <PIDS obtained from the previous command>

Run the following command to refresh the configurations:

sudo /opt/cloudera/cm-agent/bin/supervisorctl -c /run/cloudera-scm-agent/supervisor/supervisord.conf reread

Start the ZooKeeper service from the Cloudera Manager UI.
