Subject [jira] [Updated] (HIVE-4901) Connection should be closed when Statement#execute() failed byTTransportException
Date Fri, 09 Aug 2013 14:41:47 GMT

     [ https://issues.apache.org/jira/browse/HIVE-4901?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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'.

{noformat}

 

  was:
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.
