Chris Nauroth commented on MAPREDUCE-5711:
------------------------------------------
Thanks for working on this! I think it's a duplicate of MAPREDUCE-1144.
Additionally, I think MAPREDUCE-5606 is a duplicate of the same issue. Can you
please take a look at MAPREDUCE-1144? If you agree that it's the same problem,
then I recommend closing this as duplicate and moving your patch over to
MAPREDUCE-1144.
