> The idea behind this would be to test hive.map.groupby.sorted.
> Since this is a new feature, it might be a good idea to run it in test mode,
> where a query property would denote that this query plan would have changed.
> If a customer wants, they can run those queries offline, compare the results
> for correctness, and set hive.map.groupby.sorted only if all the results are
> the same.
