Harsh J commented on MAPREDUCE-3947:
------------------------------------
I think the default AM memory is also under review. Do we really need 2 GB
defaults for the AM?
Perhaps you can mark this as dupe of MAPREDUCE-3812 and improve upon Vinod's
patch on that, which sorta lowers configs (still a good place to add to xml)?
