[jira] [Created] (HIVE-6007) Make the output of the reduce side plan optimized by the correlation optimizer more reader-friendly.

Yin Huai created HIVE-6007:
------------------------------

             Summary: Make the output of the reduce side plan optimized by the correlation optimizer more reader-friendly.
                 Key: HIVE-6007
                 URL: https://issues.apache.org/jira/browse/HIVE-6007
             Project: Hive
          Issue Type: Sub-task
            Reporter: Yin Huai
            Assignee: Yin Huai
            Priority: Minor


Because a MuxOperator can have multiple parents, the output of the plan can show the sub-plan starting from this MuxOperator multiple times, which makes the reduce side plan confusing. An example is shown in https://mail-archives.apache.org/mod_mbox/hive-user/201312.mbox/%3CCAO0ZKSjniR0z%2BOt4KWouq236fKXo%3D5nE_Oih7A87e3HiuBsG9w%40mail.gmail.com%3E.
