Thomas Graves commented on YARN-460:
------------------------------------
Also note that I manually tested this by delaying the kill container message
going to AM and sleeping between when the app is marked done and before it was
removed from the application list. I was able to reproduce the issue, then
saw this patch fix it and the AM get the reboot command. I tested both
capacity scheduler and fifo.
> CS user left in list of active users for the queue even when application
> finished

> We have seen a user get left in the queues list of active users even though
> the application was removed. This can cause everyone else in the queue to get
