> Currently, Connection is not closed when Statement#execute() failed by TTransportException
due to shutdown hiveserver. It means this connection can't be used but connection status is
still 'not closed'. It might be clear that query execution got 'Connection Closed' exception
if try to use this connection. 
> {noformat}
> Scenario is as following:
> 1. Client connect hiveserver.
> 2. Hiveserver shutdown.
> 3. Client execute query: throw 'Socket' exception and close connection.
> 4. Hiveserver start.
> 5. Client execute query: throw 'Connection Closed' exception.
> 6. May be reconnect.
