>
> If the heap occupancy of a RegionServer is beyond a configurable high water
> mark (suggestions: 95%, 98%) then we should reject all user RPCs and only
> allow administrative RPCs until occupancy has dropped below a configurable
> low water mark (suggestions: 92%).
> Implement building on the HBASE-5162 changes.
> It might be expensive to check heap occupancy, in which case we can sample it
> periodically with a chore and use the last known value in pushback
> calculations.
