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.

> 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 
> less resources if using the minimum user limit percent config.
