> A number of useful numbers are emitted via the FSNamesystem JMX, but not through the
metrics system. These would be useful to be able to track over time, e.g. to alert on via
standard metrics systems or to view trends and rate changes:
> * NumLiveDataNodes
> * NumDeadDataNodes
> * NumDecomLiveDataNodes
> * NumDecomDeadDataNodes
> * NumDecommissioningDataNodes
> * NumStaleStorages
> This is a simple change that just requires annotating the JMX methods with {{@Metric}}.
