> Follow-up of HIVE-15211.
> Currently, we have some restrictions on the predicates that we can use in ON clauses
for outer joins.
> This patch is an extension to overcome these restrictions. Follow-up work will focus
on identifying some cases, such as disjunctive predicates, that can be run more efficiently
than with a cartesian product.
> It will allow to write queries that currently fail in Hive such as:
> {code:sql}
> -- Disjunctions
> SELECT *
> FROM src1 LEFT OUTER JOIN src
> ON (src1.key=src.key
>   OR src1.value between 100 and 102
>   OR src.value between 100 and 102)
> LIMIT 10;
> -- Conjunction with multiple inputs references in one side
> SELECT *
> FROM src1 RIGHT OUTER JOIN src
> ON (src1.key+src.key >= 100
>   AND src1.key+src.key <= 102)
> LIMIT 10;
> -- Conjunct with no references
> SELECT *
> FROM src1 FULL OUTER JOIN src
> ON (src1.value between 100 and 102
>   AND src.value between 100 and 102
>   AND true)
> LIMIT 10;
> {code}
