> When doing an intra stack-version upgrade/downgrade, ambari-server persists
> config-tags to use at the time of upgrade request. This is problematic when
> the upgrade process then changes configs, as the persisted commands have the
> stale tags.
> This is manifested in the case where Hive service upgrade from HDP-2.3.x
> stack-version to HDP-2.3.y stack-version results in HiveServer component not
> starting as both the old and new components use the same configs and conflict
> on the {{hive.server2.thrift.port}} value. The original port is generally
> 10000 and the new port should be 10010. However due to stale configs, both
> the old and new components conflict over the port and the new component does
> not start.
