> Before HBASE-18036, SSH would use round-robin to re-distribute regions during processing.  Round-robin assignment would loss data locality.  HBASE-18036 retains data locality if the dead region server has already restarted when the dead RS is processing.  
> With Proc-V2 based AM, the change of HBASE-18036 in Apache HBASE 1.x releases is no longer possible.  We need to implement the same logic under Proc-V2 based AM.
