> 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'. 
> Close connection and throws 'connection is closed' exception from next approach.  
> {noformat}
> Scenario is as following:
> 1. Client connect hiveserver.
> 2. Hiveserver shutdown.
> 3. Client execute query.
>    >>> Client got TTransportException and Connection is closed.
> 4. Hiveserver start.
> 5. Client execute query
>    >>> Client got exception messages 'Can't create statement, Connection is closed'.
