Review request for Ambari, Dmytro Grinenko and Nate Cole.
Bugs: AMBARI-20065
https://issues.apache.org/jira/browse/AMBARI-20065
Repository: ambari
Description
-------
Configuration changes made during an EU before pushing the stack forward are
not reverted on downgrade. For this reason, all configuration changes done
during an EU should be after all services have stopped and the stack has been
pushed to the new version.
# Deployed cluster with Ambari 2.4.2.0-136 and HDP version: 2.5.3.0-37
# Upgrade Ambari to 2.5.0.0-863
# Perform EU to 2.6.0.0 and at finalize screen, start downgrade
# Let downgrade complete
# Observe the status of Livy Server after downgrade is successful
*Result:*
Livy server reports down and log says:
{code}
17/02/10 15:10:44 INFO LivyServer: Using spark-submit version 1.6.2
17/02/10 15:10:46 INFO LivyServer: SPNEGO auth enabled (principal =

On Livy host, I see the following keytab:
