Sorry for another dump question. As I am querying such information in client code, how to get a HRegionServer from a HRegionInfo, or HServerAddress?
I found a way to get HRegionInterface shown below. HConnection.getHRegionConnection(HServerAddress) But getMetrics method is not exposed on HRegionInterface and only on HRegionServer.
