Todd Lipcon commented on MAPREDUCE-2328:
----------------------------------------
Seems we are still missing mapreduce.map.memory.mb,
mapreduce.map.memory.physical.mb, etc from mapred-default.xml.
I think the descriptions could also be improved. Take a look at
src/docs/src/documentation/content/xdocs/cluster_setup.xml in the common repo
for pretty good descriptions, as well as [this
