>
> If a region server cannot contact the master after a configurable number of
> tries, it should shut itself down.
> If the region server cannot contact the master,
> - if the master is alive but the network is partitioned, the master will
> probably time out the region server's lease and try to recover the server's
> log and reassign the regions the server is serving.
> - if the master has died, and subsequently restarts, it will be reassigning
> regions anyway, so the region server should stop serving the regions.
