Description
This is valid protobuf:
message Something {
EmptyMessage outerEmptyMessage = 1;
}
message EmptyMessage {
}
However when we try to convert this to Parquet we get:
org.apache.parquet.schema.InvalidSchemaException: Cannot write a schema with an empty group: optional group outerEmptyMessage = 1 {
}
Is this a limitation of the Parquet format, or just a bug?
If the former, can we break earlier when generating the schema out of Protobuf, and not when trying to write the content to the already generated schema?
