    Description

      Regionservers should report detailed health to master. The master should flag troubled regionservers in the UI.

      The concern at the moment is primarily heap. Regionservers should report used, committed, and max heap metrics in the periodic report. The master should flag in the regionserver list on /master.jsp those regionservers where available heap is below a configurable threshold.
