Allen Wittenauer commented on HDFS-850:
---------------------------------------

This same code path should be added to the JobTracker.  Is there an equivalent JIRA for it?

> With the HDFS-94 being commited, the namenode will use JMX memory beans to get information
about heap usage.
> They provide us with additional information such as NonHeap memory usage and Heap Commited
and Initialized memory in addition to Used and Max.
> It will be useful to see that additional information on the NameNode web ui.
