"The MRAppMaster died before writing anything."

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.
