------------------------------------
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.
