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

             Summary: Need to disable hybrid grace hash join in llap mode except for dynamically
partitioned hash join
                 Key: HIVE-13343
                 URL: https://issues.apache.org/jira/browse/HIVE-13343
             Project: Hive
          Issue Type: Bug
          Components: llap
    Affects Versions: 2.1.0
            Reporter: Vikram Dixit K
            Assignee: Vikram Dixit K


Due to performance reasons, we should disable use of hybrid grace hash join in llap when dynamic
partition hash join is not used. With dynamic partition hash join, we need hybrid grace hash
join due to the possibility of skews.
