Robert Joseph Evans commented on MAPREDUCE-4350:
------------------------------------------------
We need to be careful with this because it is a non-backwards compatible
change. I don't think that it will end up being a big deal, but if someone's
program need permissions on the files to be writable it will stop working. It
is minor enough I think documentation is probably sufficient, but I really
don't know for sure.
