Vinod Kumar Vavilapalli resolved MAPREDUCE-1396.
------------------------------------------------
    Resolution: Won't Fix

We haven't done a 1.x release in ~2 years. Unlikely this issue is going to be fixed/released.

This is less of a concern in 2.x, ResourceManager isn't that heavy on memory usage. We can file a new ticket when needed.

Closing this as Won't Fix. Please revert back if you disagree. Thanks.

> HDFS-850 is introducing changes to the NameNode web UI to display additional details of memory information. I think it will be good to have similar information for the jobtracker as well, particularly for heavily used clusters that run the risk of the masters running out of memory.
