Summary: CBO (Calcite Return Path): DUMMY project in plan
Key: HIVE-11252
URL: https://issues.apache.org/jira/browse/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.
