scala val results =sqlContext.sql(select movies.title, movierates.maxr,
movierates.minr, movierates.cntu from(SELECT ratings.product,
max(ratings.rating) as maxr, min(ratings.rating) as minr,count(distinct
user) as cntu FROM ratings group by ratings.product )

operations (such as the join) could reorder the tuples.
