> 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.
