Changing the default Java version to 8

As JDK 11 is no longer supported in Cloudera Runtime 7.3.1, you need to change the default Java version to 8 to be able to upgrade to Cloudera Runtime 7.3.1.

You can change the default Java version from 11 to 8 for your Data Lake and Cloudera Data Hub cluster on Cloudera Management Console.
  1. Navigate to the Upgrade tab of your Data Lake and Cloudera Data Hub cluster.
  2. Select the Default Java Version tab.
  3. Choose Java 8 as the Target Default Java Version.
  4. Check the Rolling restart services box to enable rolling restart for the Data Lake and Cloudera Data Hub services.
  5. Click Set Default Java Version.
Use the following command to change the default Java version for the Data Lake:
cdp datalake set-default-java-version --cluster-crn [***CRN***] --java-version 8
Use the following command to change the default Java version for the Cloudera Data Hub cluster:
cdp datahub set-default-java-version --cluster-crn [***CRN***] --java-version 8
