---------------------------------
I think the following PR resolves your issue:
https://github.com/apache/spark/pull/10490
Right?
> During join Spark should pushdown predicates on joining column to both tables
> -----------------------------------------------------------------------------
>
> Key: SPARK-12845
> URL: https://issues.apache.org/jira/browse/SPARK-12845
> 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.
