Joris Van den Bossche commented on ARROW-5205:
----------------------------------------------
Will take a look at it. We certainly did some effort on this topic in the
datasets (eg we now have a {{pyarrow.fs._resolve_filesystem_and_path}} that has
some logic to check if a plain path is available as a local file or not), but I
don't know for sure if we already use this helper in all IO methods (eg from a
quick check, I think {{feather.read_feather}} doesn't use that).

> 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"
