[jira] [Created] (HIVE-8601) Fix auto_sortmerge_join_16 determinism

Szehon Ho created HIVE-8601:
-------------------------------

             Summary: Fix auto_sortmerge_join_16 determinism
                 Key: HIVE-8601
                 URL: https://issues.apache.org/jira/browse/HIVE-8601
             Project: Hive
          Issue Type: Test
            Reporter: Szehon Ho
            Assignee: Szehon Ho


Auto_sortmerge_join_16.q results are not deterministic, as it spawns multiple mapper to do the SMB (there's no reducer).  It also has high concurrency (12 buckets in each table).
