-----------------------------------------
Hello
I have created a PR with such a functionality for SparkSQL here:
https://github.com/apache/spark/pull/2939
> let hive support theta join
> ---------------------------
>
> Key: HIVE-556
> URL: https://issues.apache.org/jira/browse/HIVE-556
> Project: Hive
> Issue Type: New Feature
> Affects Versions: 0.4.0
> Reporter: Min Zhou
> Assignee: Brock Noland
>
> Right now , hive only support equal joins . Sometimes it's not enough, we
> must consider implementing theta joins like
> {code:sql}
> SELECT
> a.subid, a.id, t.url
> FROM
> tbl t JOIN aux_tbl a ON t.url rlike a.url_pattern
> WHERE
> t.dt='20090609'
> AND a.dt='20090609';
> {code}
> any condition expression following 'ON' is appropriate.
