    Description

      The design in HBASE-20424 implies that, when transiting from A to S, the RS will abort and the WAL file will be split.

      But in fact, there could be races that make a RS still alive after the transiting which causes data inconsistency. And also, a full cluster restart is expensive, we need to find a more smooth way.
