> In a number of places if a string filepath is passed, it is assumed to be a
> local file. Since we are developing better support for file URIs, we may be
> able to detect that the user has passed an unsupported URI (e.g. something
> starting with "s3:" or "hdfs:") and return a better error message than "local
> file not found"
