> URL: https://issues.apache.org/jira/browse/HBASE-12731
> Project: HBase
> Issue Type: New Feature
> Reporter: Andrew Purtell
> Assignee: Andrew Purtell
> Fix For: 2.0.0, 0.98.10, 1.1.0
>
> Attachments: HBASE-12731-0.98.patch, HBASE-12731-0.98.patch,

>
> 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.
