             Summary: NullScanTaskDispatcher should use stats
                 Key: HIVE-24350
                 URL: https://issues.apache.org/jira/browse/HIVE-24350
             Project: Hive
          Issue Type: Improvement
            Reporter: Mustafa Iman
            Assignee: Mustafa Iman


NullScanTaskDispatcher manually checks each partition directory to see if they 
are empty. While this is necessary in external tables, we can just use stats 
for managed tables.
