> NodeFailoverWorker takes the dead rs znode and starts processing it (moving the log znodes under it, etc). 
> Even a regionserver restart will trigger this znodes movement. This cause some other regionserver to read the log files remotely, even though, the original regionserver is up. Ideally, it should check available regionserver znodes after it comes out it sleep in its run method in order to decide whether it should really process the znode or not.
