Vinod Kumar Vavilapalli updated MAPREDUCE-3720:
-----------------------------------------------

    Description: 
When the RM has a large number of jobs, {{bin/mapred job -list}} takes a long time as it visits each AM to get information like num-maps, num-reduces etc.

We should move all per-AM information to {{bin/mapred job -status}} and keep the list just a list.
