             Summary: AST is corrupted after CBO fallback for CTAS queries
                 Key: HIVE-25770
                 URL: https://issues.apache.org/jira/browse/HIVE-25770

          Issue Type: Bug

         Attachments: repro.q

reproduce:
* revert ec44c6081c88b81245185fa6a552d8c3631e47fa to force cbo fallbacks for >64 grouping sets

* but with cbo enabled it would fail in conservative mode as well
