Hari Sekhon commented on AMBARI-13168:
--------------------------------------
This same problem appears when trying to restart HiveServer2 in the Hive
service, made worse by the fact that reverting to the previous configuration
exposes another bug where Ambari is still trying to use Ranger keys
(AMBARI-13189).
This error given for restarting the Hive service which breaks on the
HiveServer2 component restart appears to be the same generic Ambari issue as it
was for Yarn:
