> I got {{Invalid parquet file. Corrupt footer.}} trying to read real data. Turned out it was because I had opened the directory in macOS Finder and it had added the junk .DS_Store files. Once I deleted them, the Dataset created fine. 
> If we're creating a DataSource with Parquet files, we should ignore any non-Parquet files we encounter when scanning.
