--------------------------------------
Summary: During join Spark should pushdown predicates 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 which have no
sense
{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.
