Vinod Kumar Vavilapalli commented on MAPREDUCE-3910:
----------------------------------------------------

Yes, your explanation is correct. I believe this happened after I moved the 
scheduler events to a separate dispatcher as part of the RM refactor. Because 
of that, the app-submission also moved to a separate thread and so the UGI 
context is lost.

Patch looks good too. +1. Pushing this in.
