                 Key: HIVE-2013
                 URL: https://issues.apache.org/jira/browse/HIVE-2013
             Project: Hive
          Issue Type: Improvement
            Reporter: Ning Zhang
            Assignee: He Yongqiang


If a query involves many partitions, checking privilege for each partition could be very expensive.
An optimization is to indicate in the partition metadata that its privilege is the same as
table level (default) privilege so that we only do 1 ACL checking for the set of partitions
having the default privilege.
