[jira] [Commented] (SPARK-17251) "ClassCastException:
OuterReference cannot be cast to NamedExpression" for correlated subquery
on the RHS of an IN operator
[ https://issues.apache.org/jira/browse/SPARK-17251?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15694381#comment-15694381 ]
Dongjoon Hyun commented on SPARK-17251:
---------------------------------------
Hi, [~hvanhovell].
The suggested solution seems to extend `OuterReference` with trait `NamedExpression` and eventually to raise the following correct exception. May I create a PR for this?
{code}
org.apache.spark.sql.AnalysisException: Correlated predicates are not supported outside of WHERE/HAVING clauses
{code}
