After you upgrade, you must test all the services that run on your platform.
Ideally, you should have an indicative subset of jobs from your workloads. These
are the tasks that you should have identified and run before the upgrade allowing you to
compare pre-upgrade versus post-upgrade test results. These tests should also include
any parts of the application that required code changes due to the changes in the
platform. For example, to cater for changes in Hive managed versus external tables. The
tests should also include a performance test. This can help to highlight missed or wrong
configuration settings or point to other issues with the upgrade. Depending on your
environment, perform these steps.
Update application code with changes required by the upgraded platform
Update the dependencies in the pom.xml file for
custom jar files used in your applications to use the new dependencies
for CDP.
Restart applications
Test the applications and verify they are functioning and performing as they were
prior to upgrade
