Suresh Srinivas commented on HDFS-4860:
---------------------------------------
There is a lot duplication of this work with NamenodeMXBean. Can you please
present an analysis of what was missing in that? Also if there are things
missing, that needs to go into NamenodeMxBean?
> Add additional attributes to JMX beans

> 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)
