             Summary: Add option in RegionMover.java to isolate one or more regions on the RegionSever
                 Key: HBASE-28168
                 URL: https://issues.apache.org/jira/browse/HBASE-28168
             Project: HBase
          Issue Type: New Feature
            Reporter: Mihir Monani
            Assignee: Mihir Monani


Sometime one or more HBase regions on RS are under high load. This can lead to resource starvation for other regions hosted on the RS. It might be necessary to isolate one or more regions on the RS so that region with heavy load doesn't impact other regions hosted on the same RS.

RegionMover.java class provides a way to load/unload the regions from the specific RS. It would be a good to have an option pass list of region hash that should be left on the RS and put the RS in the draining/decommission mode so HMaster doesn't assign new regions on the RS.
