Subject [jira] [Commented] (HIVE-4641) Support post execution/fetch hook for HiveServer2
Date Thu, 06 Jun 2013 01:38:22 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4641?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13676588#comment-13676588

Carl Steinbach commented on HIVE-4641:
--------------------------------------

Ok, but can you give me an actual example of something that requires this functionality?

What kind of information do you plan to make available to the hook?

I also think we need to be really careful about providing a way for people to mutate the resultset
after it has been generated since this work will be done on the server node in a non-distributed
fashion.

> Support post execution/fetch hook that is invoked prior to returning results to the client.
This can be used to filter results before returning the result set to the client.
