> If we aim to make Hive compliant with SQL, w should disable this property by default,
as expressing a cartesian product, though inefficient, is perfectly valid in SQL.
> Further, if we express complex predicates in the ON clause of a SQL query, we might not
be able to push these predicates to the join operator; however, we should still be able to
execute the query.
