> We will check whether server carrying ROOT/META when expiring the server.
> See ServerManager#expireServer.
> If the dead server carrying META, we assign meta directly in the process of
> ServerShutdownHandler.
> If the dead server carrying ROOT, we will offline ROOT and then
> verifyAndAssignRootWithRetries()
> How judgement of carrtying ROOT/META become wrong?
> If region is in RIT, and isCarryingRegion() return true after addressing from
> zk.
> However, once RIT time out(could be caused by this.allRegionServersOffline &&
> !noRSAvailable, see AssignmentManager#TimeoutMonitor) and we assign it to
> otherwhere, this judgement become wrong.
> See AssignmentManager#isCarryingRegion for details
> With the wrong judgement of carrtying ROOT/META, we would assign ROOT/META
> twice.
