See HIVE-23963. Replace this when this is fixed in calcite. Review comment: If it is meant to be fixed in Calcite then we should create a JIRA and add an entry in `org.apache.hadoop.hive.ql.optimizer.calcite.Bug`. We could even skip the JIRA creation and move this comment in `Bug` as `CALCITE-X0000_fixed` or something similar. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
