Subject [jira] [Created] (HIVE-10864) CBO (Calcite Return Path): auto_join2.q returning wrong results

             Summary: CBO (Calcite Return Path): auto_join2.q returning wrong results
                 Key: HIVE-10864
                 URL: https://issues.apache.org/jira/browse/HIVE-10864
             Project: Hive
          Issue Type: Sub-task
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


auto_join2.q returns wrong results when return path is on. The problem is that we create the
same join expression once per input reference when we are translating. Thus, we incorrectly
end up with a key composed by multiple expressions in those cases.
