----------------------------------
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.
