> Steps to generate the error:
> 1. Setup a queue with 1 max active application per user
> 2. Submit a long running job to this queue.
> 3. Submit another job to the queue as the same user. Access the tracking URL
> for job 2 directly or via Oozie (not via the RM link - which is rewritten once
> the app starts).
> This would exist in situations where the queue doesn't have enough capacity -
> or for the small period of time between app submission and AM start.
