> 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.
