> ThriftSchemaConverter should either only be called on ThriftStruct's that
> have populated structOrUnionType metadata, or should support a mode where
> this data is unknown w/o throwing an exception.
> Currently it is called using the file's metadata here:
> https://github.com/apache/parquet-mr/blob/d6f082b9be5d507ff60c6bc83a179cc44015ab97/parquet-thrift/src/main/java/org/apache/parquet/thrift/ThriftRecordConverter.java#L797
> One workaround is not not use the file matadata here but rather the schema
> from the thrift class. The other is to support unknown struct or union types
