             Summary: Disable CollapseProject for correlated subqueries in projection over aggregate correctly
                 Key: SPARK-49819
                 URL: https://issues.apache.org/jira/browse/SPARK-49819

          Issue Type: Bug
          Components: Optimizer
    Affects Versions: 4.0.0
            Reporter: Nick Young


CollapseProject should block collapsing with an aggregate if any correlated subquery is present. There are other correlated subqueries that are not ScalarSubquery that are not accounted for here.
