> It is possible that the reportRegionStateTransition method is succeeded at
> master side, but before returning the the region server, the rpc connection
> is broken, or the master restarts. So next when the region server try
> again,we will find that the state for the region and the TRSP is not correct,
> and can lead to a RS abort or something even worse.
> We should be able to determine whether a reportRegionStateTransition call is
> just a retry and has already been succeeded, and just ignore it.
