Subject [jira] [Created] (SPARK-21835) RewritePredicateSubquery should not produce unresolved query plans
Date Fri, 25 Aug 2017 05:37:00 GMT
Liang-Chi Hsieh created SPARK-21835:
---------------------------------------

             Summary: RewritePredicateSubquery should not produce unresolved query plans
                 Key: SPARK-21835
                 URL: https://issues.apache.org/jira/browse/SPARK-21835
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: Liang-Chi Hsieh


{{RewritePredicateSubquery}} rewrites correlated subquery to join operations. During the structural
integrity, I found {[RewritePredicateSubquery}} can produce unresolved query plans due to
conflicting attributes. We should not let {{RewritePredicateSubquery}} produce unresolved
plans.
