Arun C Murthy updated MAPREDUCE-2687:
-------------------------------------
Attachment: MAPREDUCE-2687.patch
With this updated patch I can run applications as other users than the mapred
user.
OTOH, there is a different bug which causes apps from other users to fail due
to an error in LTC:

Still tracking this down... I wonder if this causes permission issues.
I've committed HADOOP-7580 which should help ease debugging.
