[jira] [Created] (HIVE-20791) Enforce a "Spill Maximum" per query

Peter Ebert created HIVE-20791:
----------------------------------

             Summary: Enforce a "Spill Maximum" per query
                 Key: HIVE-20791
                 URL: https://issues.apache.org/jira/browse/HIVE-20791
             Project: Hive
          Issue Type: New Feature
          Components: Configuration
            Reporter: Peter Ebert


Currently one query that spills excessively to disk can use up all cluster space and cause other queries/workloads to fail.  I understand that a global maximum would be difficult to track, but some limit per mapper/reducer would help keep the spill under control.
