> 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.
