> Problem
> These are number widgets on Grafana and is expected to show point in time 
> information for "Average Regions per RegionServer" 
> ambari-web that shows expected correct information gets the data from 
> "Hadoop:service=HBase,name=Master,sub=Server.averageLoad" jmx metric via 
> ambari-server metrics API resource.
> It seems having aggregator as "avg" looks to be causing this issue. when 
> there are more than one HBase master than the metric value is averaged across 
> all masters
