>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.6.0
>            Reporter: Maciej Bryński
>
> I have following issue.
> I'm connecting two tables with where condition
> {code}
> select * from t1 join t2 in t1.id1 = t2.id2 where t1.id = 1234
> {code}
> In this code predicate is only push down to t1.
> To have predicates on both table I should run following query:
> {code}
> select * from t1 join t2 in t1.id1 = t2.id2 where t1.id = 1234 and t2.id2 = 1234
> {code}
> Spark should present same behaviour for both queries.
