> Hive's grouping__id method made a change since hive version 2.3.0. Now spark
> does not declare this inconsistency with Hive, which may make user believe
> they're safe from migrating their query from Hive 1.x to Spark, but which is
> wrong.
> I guess we should note this difference in Hive migration guide, and add a
> configuration to let grouping__id to use hive 1.x compatible algorithm
