Known issues in 7.1.9 CHF 2

You must be aware of the known issues and limitations, the areas of impact, and workaround in Cloudera Runtime 7.1.9 CHF 2.

OPSAPS-69539: CDP Runtime 7.1.9 from the base release through to CHF3 does not support Oracle JDK 8u401 or OpenJDK 1.8.0_402 (8u402). Some services will fail to start. This can be a problem on RHEL 9.x as version 8u402 is the default OpenJDK 8 installed by the OS.
Workaround is to install an earlier version of JDK 8. For example Oracle jdk-8u291 / 1.8.0_291, or OpenJDK 8u292 / 1.8.0_292.
A fresh install of 7.1.9 CHF 2 does not allow user to bypass the Setup Database screen for YARN Queue Manager
YARN Queue Manager in Cloudera Data Platform (CDP) Private Cloud Base 7.1.9 CHF 2 does not require you to install a PostGres database, therefore users should not see the Setup Database screen and should be able to skip the Setup Database screen. With this known issue, users who are conducting a fresh install of 7.1.9 CHF 2 are not able to bypass the Setup Database screen as expected.
  1. When conducting a fresh install of YARN Queue Manager in 7.1.9 CHF 2, you must ensure that you have both CDP and Cloudera Manager upgraded to 7.1.9 CHF 2.
  2. When you reach the Setup Database screen in the Cloudera Manager installation wizard for Queue Manager, enter any dummy values for the following fields:
    1. Database name: configstore
    2. Database Username: dbuser
    3. Database Password: dbpassword
    YARN Queue Manager will not connect to PostGres with the above details and will fall back to the embedded database.
  3. Run the following script command in a browser console to enable the Continue button:

    document.querySelector('.btn.next').removeAttribute('disabled');

  4. Click Continue and proceed with the YARN Queue Manager installation.
  5. After installation is complete, SSH into the host that has Queue Manager installed, and run this command: sed -i 's/migrationCompleted=true/migrationCompleted=false/' /var/lib/hadoop-yarn/migration.properties
  6. Restart YARN Queue Manager.
