> With the HDFS-94 being commited, the namenode will use JMX memory beans to

> 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.
