@cloud-fan We have had users writing data with empty schemas in production and changing the schema of a non-trivial number of rows seems like a big change. Spark allows creating empty schemas ad supports reading them, it might be fitting to consider writing out empty schemas. This PR adds a legacy configuration so that users can choose to ignore the validation check to restore old behavior. What are your thoughts on this ?
