Nate Cole created AMBARI-17904:
----------------------------------

             Summary: Downgrade Schedules Manual & Configuration Tasks For Components Which Didn't Upgrade
                 Key: AMBARI-17904
                 URL: https://issues.apache.org/jira/browse/AMBARI-17904
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Nate Cole
            Assignee: Nate Cole
            Priority: Critical
             Fix For: 2.4.0


STR:
- Install HDP 2.4 with Storm and start an EU to 2.5
- On the first manual task, click downgrade right away

You'll notice that in addition to the 2 or 3 "normal" downgrade tasks, Storm is also scheduled. There are 2 manual tasks which are scheduled for SUPERVISOR and DRPC_SERVER.

It looks like the cause of this is a bug in the {{TaskWrapperBuilder}} which schedules tasks for {{MANUAL}} and {{CONFIGURE}} regardless of whether any hosts resolved.
