Just check what Java version you are using. Important: For JDK 8u241 and higher versions running on Kerberized clusters, you must disable referrals by setting sun.security.krb5.disableReferrals=true. For example, with OpenJDK 1.8.0u242: Open /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/jre/lib/security/java.security with a text editor. Add sun.security.krb5.disableReferrals=true (it can be at the bottom of the file). Add this property on each node that has the impacted JDK version. Restart the applications using the JDK so the change takes effect. For more information, see the KB article.

@seanbenner Try the "IDLE_MAXIMUM_MINUTES" engine variable from below doc if this helps. https://docs.cloudera.com/cdsw/1.9.2/environment-variables/topics/cdsw-engine-environment-variables-1.html

@Sha2Nk You mean individual Apache Services like HDFS and Hive etc then that's not possible. However the CSD based services like CDSW and Spark etc can be upgraded. Hope I get your questions correctly.

@wert_1311 No downtime needed. Only agent CM agent restart on Hue servers may required if you see the alternative not taking effect.

@aval Run the rpm -qa | grep -i cloudera on the host and send the output also confirm the Java version being used. I am wondering if you can just simply install the openjdk on host and try installing the cluster. That should work.

@CDPTester Please go through the below doc thoroughly and plan the upgrade. https://docs.cloudera.com/cdp-private-cloud-upgrade/latest/upgrade-cdh6/topics/cdpdc-cdh6-overview.html This doc should have all the step by step procedure and prerequisite for upgrade.

@aval Can you tell me which doc you are following and are you adding 2nd cluster in the same CM? There should be repo file in this location.
