Mihir Monani updated HBASE-28168:
---------------------------------
Description:
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 to pass list of region hash
that should be left (or moved) on the RS and put the RS in the
draining/decommission mode so HMaster doesn't assign new regions on the RS.
Ex.
{code:java}
--isolateRegionIds regionHash1,regionHash2,regionHash3{code}
