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.
