【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-rhel-custom-location.html 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.
