> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 2.9.0, 3.0.0-alpha4
> Reporter: Tao Yang
> Assignee: Tao Yang
> Priority: Major
> Fix For: 3.2.0, 3.1.1, 3.0.3

>
> DRAINING state is a temporary state in RM memory, when queue state is set to
> be STOPPED but there are still some pending or active apps in it, the queue
> state will be changed to DRAINING instead of STOPPED after refreshing queues.
> We've encountered the problem that the state of this queue will aways be
> STOPPED after RM restarted, so that it can be removed at any time and leave
> some apps in a non-existing queue.
> To fix this problem, we could recover DRAINING state in the recovery process
> of pending/active apps. I will upload a patch with test case later for review.
