      Description

      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.
