### Rationale for this change A non-nullable column that contains nulls would result in an invalid Parquet file, so we'd rather raise an error when writing. This detection is only implemented for leaf columns. Implementing it for non-leaf columns would be more involved, and also doesn't actually seem necessary. ### Are these changes tested? Yes. ### Are there any user-facing changes? Raising a clear error when trying to write invalid data to Parquet, instead of letting the Parquet writer silently generate an invalid file. -- This is an automated message from the Apache Git Service.
