             Summary: De-duplicate semijoin branches in n-way joins
                 Key: HIVE-16441
                 URL: https://issues.apache.org/jira/browse/HIVE-16441
             Project: Hive
          Issue Type: Task
            Reporter: Deepak Jaiswal
            Assignee: Deepak Jaiswal


Currently in n-way joins, semi join optimization creates n branches on same key. Instead it
should reuse one branch for all the joins.
