> When a regionservers is stopped (shutdown or crash) and on the same moment a client performs
a scan on that regionserver no exception is thrown at client side nor a reconnect toanother
regionsserver is tried.
> The ResultScanner.Iterator.hasNext ()just returns false, so the client assumes that there
are no records anymore.
> In the ScannerCallable.call I notice that the java.net.ConnectionException is catched
and a empyt Result array is returned.
