> Currently Hive users have to do nested queries in order to apply filter on
> group by expressions.
> This patch allows users to directly apply filter on group by expressions by
> using HAVING clause.
> This patch also helps us integrate Hive with other data analysis tools which
> rely on HAVING expression.
