> If exception happens during we try to get the connection from HiveDriver,
> the opened transport or session may leave unclosed as the connection returned
> is null, we cannot call the close method to release the server
> resources(threads, connection quota, etc.), this could make things more worse
> if the user rearches the connection limit and retries...
