> 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.
