Subject [jira] Commented: (HIVE-78) Authorization infrastructure for Hive
Date Wed, 29 Dec 2010 03:52:36 GMT

    [ https://issues.apache.org/jira/browse/HIVE-78?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12975710#action_12975710

Namit Jain commented on HIVE-78:
--------------------------------

I think you can do the following optimization: feel free to do it in a followup.

There are many queries which have lots of input partitions for the same input table.
If the table under consideration has the same privilege for all the partitions, you
dont need to check the permissions for all the partitions. You can find the common
tables and skip the partitions altogether
