                 Key: HIVE-12518
                 URL: https://issues.apache.org/jira/browse/HIVE-12518
             Project: Hive
          Issue Type: Sub-task
            Reporter: Pengcheng Xiong
            Assignee: Pengcheng Xiong


The problem can be reproduced when there is no map group by and the data is skewed for return path.
