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
