Arun C Murthy updated MAPREDUCE-3720:
-------------------------------------
Resolution: Fixed
Release Note:
Changed bin/mapred job -list to not print job-specific information not
available at RM.
Very minor incompatibility in cmd-line output, inevitable due to MRv2
architecture.
Hadoop Flags: Incompatible change,Reviewed
Status: Resolved (was: Patch Available)
I just committed this. Thanks Vinod!

> 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.
