Peter Bacsko commented on MAPREDUCE-6898:
-----------------------------------------
[~jlowe] I just realized that this problem has already been solved by Haibo
Chen:
https://github.com/apache/hadoop/commit/0cfd7ad21f4457513ed3416e5d77f3123bfe9da0
Originally we detected this problem on a different branch and when I rebased my
changes against apache/trunk I didn't see that there is already a solution :)
You might want to revert this commit.
