Subject [jira] [Created] (HIVE-11252) CBO (Calcite Return Path): DUMMY project in plan
Date Tue, 14 Jul 2015 13:57:04 GMT
Jesus Camacho Rodriguez created HIVE-11252:

             Summary: CBO (Calcite Return Path): DUMMY project in plan
                 Key: HIVE-11252
             Project: Hive
          Issue Type: Sub-task
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez

When the return path is on, we might end up with a Project with DUMMY column in the plan;
thus, we need to run the ProjectMergeRule after the column trimmer runs for the second time.
