> After [HIVE-19653|https://issues.apache.org/jira/browse/HIVE-19653], filters
> with only columns and constants are pushed down, but in some cases, this may
> not work as well, for example:
> SET hive.cbo.enable=false;
> SELECT a, b, sum(s)
> FROM T1
> GROUP BY a, b GROUPING SETS ((a), (a, b))
> HAVING upper(a) = "AAA" AND sum(s) > 100;
>
> SELECT upper(a), b, sum(s)
> FROM T1
> GROUP BY upper(a), b GROUPING SETS ((upper(a)), (upper(a), b))
> HAVING upper(a) = "AAA" AND sum(s) > 100;
>
> The filters pushed down to GBY can be f(gbyKey) or gbyKey with udf , not
> only the column groupby keys.
