Miles Granger commented on ARROW-18225:
---------------------------------------
nvm, think I see the issue there. ``where`` in this case would be an s3 path.
Not the local or file-like obj that method (write_metadata_file) wants.
> [Python] write_metadata does not fully use **kwargs

> When using {{write_metadata}}, {{kwargs}} can be used to pass a FileSystem to
> a ParquetWriter. However, those {{kwargs}} are not passed to
> {{read_metadata}} later on despite the function accepting a filesystem
> argument.
> This creates an error when trying to write metadata on a S3FileSystem for
> example.

> def write_metadata(schema, where, metadata_collector=None, **kwargs):
> writer = ParquetWriter(where, schema, **kwargs)
> writer.close()
> if metadata_collector is not None:
> metadata = read_metadata(where) # kwargs should be passed here
