Rui Li updated FLINK-22726:
---------------------------
Description:
Hive's GROUPING__ID changed since 2.3.0. In current implementation we use
Calcite's GROUPING_ID operator which yields same value as hive >= 2.3.0. When
integrate with older hive, we should follow the previous behavior.
Refer to:
https://issues.apache.org/jira/browse/HIVE-16102

> Hive GROUPING__ID returns different value in older versions
