[jira] [Created] (SPARK-1889) Apply splitConjunctivePredicates to join condition while finding join keys.

Takuya Ueshin created SPARK-1889:
------------------------------------

             Summary: Apply splitConjunctivePredicates to join condition while finding join keys.
                 Key: SPARK-1889
                 URL: https://issues.apache.org/jira/browse/SPARK-1889
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Takuya Ueshin


When tables are equi-joined by multiple-keys {{HashJoin}} should be used, but {{CartesianProduct}} and then {{Filter}} are used.
The join keys are paired by {{And}} expression so we need to apply {{splitConjunctivePredicates}} to join condition while finding join keys.
