cloud-fan commented on issue #23726: [SPARK-26812][SQL] Report correct nullability for complex datatypes in Union URL: https://github.com/apache/spark/pull/23726#issuecomment-462601482 since we are touching `Union`, I'm wondering if we should just create new output attribubutes for `Union`, instead of reusing the first child's output. cc @gatorsmile
