> Currently when users try to use nullable Avro schemas for non-nullable data in Avro writing, Spark will throw a IncompatibleSchemaException.
> There are some cases when users do not have full control over the nullability of the data, or the nullability of the Avro schemas they have to use. We should support nullable Avro schemas for non-nullable data in Avro writing for better usability.
