Daniel Templeton commented on MAPREDUCE-6715:
---------------------------------------------
LGTM. About that pointless null check... If it's there to make a code
analyzer happy, I'm OK with that. It might be good to add a comment to explain
that, though, so that someone else doesn't remove it later.
