Github user hvanhovell commented on the issue: https://github.com/apache/spark/pull/21388 @HeartSaVioR I really don't think we should automate these things at all. The planner is a pretty critical component, and I'd rather be explicit on how a `LogicalPlan` maps to a `SparkPlan` and have the benefit of compile time checks, then have some reflection glue doing this at runtime (which can potentially blow up). What is the problem you are trying to solve here?
