[jira] [Commented] (HIVE-4641) Support post execution/fetch hook for HiveServer2

    [ https://issues.apache.org/jira/browse/HIVE-4641?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13676367#comment-13676367 ] 

Shreepadma Venugopalan commented on HIVE-4641:
----------------------------------------------

Enforcing security on a per row basis could be one use of such a hook. The hook can be used in other ways to apply custom transformations to the result set before returning to the client.

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