Aaron T. Myers commented on HDFS-3678:
--------------------------------------
I'd like to merge this change to branch-2 as well. It's not strictly necessary
because this bug doesn't exist in branch-2, but merging this restructuring of
the code to branch-2 will make future merges in related code easier.
If I don't hear any objections I'm going to do this late today some time, so
please speak up.
