   I poked around at this a bit.  The error seems to be that write_dataset is creating files with the application/xml content type and then `minio.s3::save_object` is trying to parse the object as XML because of this content type.  I'm not entirely sure why application/xml is being set (I'm pretty sure we default in Arrow to not setting the content type at all) so I'll look into that a bit more.
   
   If I hardcode the C++ to set the content-type to something else (application/parquet) then minio.s3::save_object works fine.
   ```
   (base) pace@pace-desktop:~$ mc stat myminio/bucket/test/part-0.parquet 
   Name      : part-0.parquet

   ```
