Description

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.
