Subject [jira] [Created] (AMBARI-12188) Intra stack-version upgrade sends stale configs in commands to hosts
Date Sun, 28 Jun 2015 03:03:04 GMT
Srimanth Gunturi created AMBARI-12188:
-----------------------------------------

             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.
