Allison Wang created SPARK-35551:
------------------------------------

             Summary: Handle the COUNT bug when rewriting lateral subqueries
                 Key: SPARK-35551
                 URL: https://issues.apache.org/jira/browse/SPARK-35551
             Project: Spark
          Issue Type: Task
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Allison Wang


Similar to SPARK-15370, When a lateral join is rewritten as a normal join, it can lead to incorrect result since the rewrite can potentially change the semantics of the query plan. Please see SPARK-15370  for more details.
