             Summary: SMB join small table side should use the same set of serialized payloads across tasks
                 Key: HIVE-8597
                 URL: https://issues.apache.org/jira/browse/HIVE-8597
             Project: Hive
          Issue Type: Improvement
          Components: Tez
    Affects Versions: 0.14.0
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth
             Fix For: 0.14.0


Each task sees all splits belonging to the bucket being processed by the task. At the moment, we end up using different instances of the same serialized split which adds unnecessary memory pressure.
