After upgrading Cloudera Manager to 7.11.3, Lily HBase Indexer fails

[#1]

【Problem】
After upgrading Cloudera Manager to 7.11.3, attempting to reboot the cluster causes an error in the Lily HBase Indexer of the Key-Value Store Indexer.

【Use】
CDP Private Cloud Base 7.1.8 (Will upgrade to 7.1.9 later)
OS: RHEL 7.6
Java: OpenJDK 11.0.8
Python: 3.8.12

【Occurrence procedure】
Before upgrading, I installed Python 3.8 on all hosts that contained Cloudera Manager Agents.
The installation was done according to the following documentation:
https://docs.cloudera.com/cdp-private-cloud-base/7.1.9/installation/topics/cdpdc-cm-install-python-3...

Then, according to the following documentation, Cloudera Manager was upgraded from 7.7.1 to 7.11.3.
https://docs.cloudera.com/cdp-private-cloud-upgrade/latest/upgrade-cdp/topics/ug_cm_upgrade.html

Verified that the Server and Agent were upgraded successfully.
Therefore, I proceeded with the steps in Step 5: After You Upgrade, "Perform Post-Upgrade Steps".
When I rebooted the cluster in step 4, I encountered an error with the Lily HBase Indexer of the Key-Value Store Indexer.

After "Reboot Cluster", all services started before this service are running normally.
Also, all hosts in the cluster are running normally.
How do you deal with this problem?

Hi @nsup This is a known issue with Py3 compatibility in hbase-indexer. This should be fixed in CDP 7.1.8 CHF6 and in CDP 7.1.9 release.
