             Summary: Can group splits in bucket map join in tez to improve 
efficiency
                 Key: HIVE-6516
                 URL: https://issues.apache.org/jira/browse/HIVE-6516
             Project: Hive
          Issue Type: Bug
          Components: Tez
    Affects Versions: tez-branch
            Reporter: Vikram Dixit K
            Assignee: Vikram Dixit K


Currently, we do not group splits while executing a bucket map join. If we can 
group the splits correctly, we can be more efficient (i.e. need less tasks in a 
particular stage)
