> Currently the JMX bean returns much of the data contained on the HDFS Health webpage (dfsHealth.html). However there are several other attributes that are required to be added.
> I intend to add the following items to the appropriate bean in parenthesis :
> Started time (NameNodeInfo),
> Compiled info (NameNodeInfo),
> Jvm MaxHeap, MaxNonHeap (JvmMetrics)
> Node Usage stats (i.e. Min, Median, Max, stdev) (NameNodeInfo),
> Count of decommissioned Live and Dead nodes (FSNamesystemState),
> Journal Status (NodeNameInfo)
