-----------------------------------------
Summary: Intra stack-version upgrade sends stale configs in
commands to hosts
Key: AMBARI-12188
URL: https://issues.apache.org/jira/browse/AMBARI-12188
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.0
Reporter: Srimanth Gunturi
Assignee: Srimanth Gunturi
Fix For: 2.1.0
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.
