---------------------------------

             Summary: Add config to block queries that scan > N number of partitions 
                 Key: HIVE-12603
                 URL: https://issues.apache.org/jira/browse/HIVE-12603
             Project: Hive
          Issue Type: Bug
          Components: Metastore, Query Planning
    Affects Versions: 2.0.0
            Reporter: Lenni Kuff


Strict mode is useful for blocking queries that load all partitions, but it's still possible
to put significant load on the HMS for queries that scan a large number of partitions. It
would be useful to add a config provide a hard limit to the number of partitions scanned by
a query.
