as table level privilege

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.
