Azrael Park updated HIVE-4901:
------------------------------
Description:
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'.

was:
