> If on master restart it finds the ROOT/META to be in RIT state, master tries
> to assign the ROOT region through ProcessRIT.
> Master will trigger the assignment and next will try to verify the Root
> Region Location.
> Root region location verification is done seeing if the RS has the region in
> its online list.
> If the master triggered assignment has not yet been completed in RS then the
> verify root region location will fail.
> Because it failed
> {code}
> splitLogAndExpireIfOnline(currentRootServer);
> {code}
> we do split log and also remove the server from online server list. Ideally
> here there is nothing to do in splitlog as no region server was restarted.
> So master, though the server is online, master just invalidates the region
> server.
> In a special case, if i have only one RS then my cluster will become non
> operative.
