Display more memory details on the web ui
-----------------------------------------
Key: HDFS-850
URL: https://issues.apache.org/jira/browse/HDFS-850
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Dmytro Molkov
Priority: Minor
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.
