Vinod Kumar Vavilapalli resolved MAPREDUCE-5606.
------------------------------------------------
Resolution: Won't Fix
I originally debugged the user.location bug with [~cnauroth].
It indeed is the same issue as MAPREDUCE-1144.
We haven't done a 1.x release in ~2 years. Unlikely this issue is going to be
fixed/released. This shouldn't happen in 2.x, which was a complete rewrite.
Closing this as Won't Fix.
