[jira] Created: (HDFS-850) Display more memory details on the web ui

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.
