Description

In HADOOP-4435, in branch 0.20, getClusterStatus() method returns JobTracker's used memory and total memory.
But these details are missed in new api (through MAPREDUCE-777).
If these details are needed only for web UI, I don't think they are needed for client.
So, should we provide a way to know JobTracker's memory info from client?
If yes, an api should be added in org.apache.hadoop.mapreduce.Cluster for the same.
