Wangda Tan commented on MAPREDUCE-6304:
---------------------------------------
[~Naganarasimha], remove from mapred-default.xml is not good.
mapred-default.xml is a way to document all options we have, how about make its
default to be "USE_QUEUE_DEFINED_DEFAULT" or better name, it's not "not
specified" or "null" actually, it's using queue defined node label expression.
Thoughts?
