---------------------------------------------

             Summary: CBO (Calcite Return Path): GroupingID translation from Calcite [CBO
branch]
                 Key: HIVE-9943
                 URL: https://issues.apache.org/jira/browse/HIVE-9943
             Project: Hive
          Issue Type: Sub-task
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


The translation from Calcite back to Hive might produce wrong results while interacting with
other Calcite optimization rules. Further, we could ease translation of Aggregate operator
with grouping sets to Hive.
