> Key: HIVE-15209
> URL: https://issues.apache.org/jira/browse/HIVE-15209
> Project: Hive
> Issue Type: Bug
> Components: Parser
> Affects Versions: 2.2.0
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
>
> 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.
