Robert Joseph Evans commented on MAPREDUCE-4371:
------------------------------------------------
The change looks good to me and the javadoc warnings appear to be caused by a
different patch. +1 I'll check this in for you. I am going to put it in trunk
because that is what the target version is set to. If you want this to go into
branch-2 I think that should be fine, just post another comment to let me know.
