An empty struct type (with no child fields) is not easy to write in Parquet, since Parquet only represents the data of leaf nodes. We would need a way to distinguish between null and non-null (empty) struct values. It would probably require a dummy primitive node. Until we implement such a solution, simply raise a nice error when an empty struct is encountered. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
