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. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
