> Project: Hadoop YARN
> Issue Type: Bug
> Components: fairscheduler
> Affects Versions: 2.4.0, 2.6.0, 2.7.1

> When moving a running application to a different queue, the current implement
> don't check if the app can run in the new queue before remove it from current
> queue. So if the destination queue is full, the app will throw exception, and
> don't belong to any queue.
> After that, the queue become orphane, can not schedule any resources. If you
> kill the app, the removeApp method in FSLeafQueue will throw
> IllealStateException of "Given app to remove app does not exist in queue ..."
> exception.
> So i think we should check if the destination queue can run the app before
> remove it from the current queue.
> The patch is from our revision.
