Excellent. Nice and clean.

Why a new exception? Why not pass the one that got us here? (Or, maybe
there isn't one? Or you can't get at it)

>
> Clients use an HConnection down in their guts to connect to the hbase
> cluster. Master-is-running and root-region-location are up in zk. Setup of
> a new HConnection sets up a connection to ZooKeeper. If the session with ZK
> expires for whatever reason -- in tests they would expire because zk ensemble
> was restarted across tests or we might expire because of a long GC, well,
> it'll be frustrating to users if we do not just try and resetup the zk
> connection.
