Francois Saint-Jacques commented on ARROW-8283:
-----------------------------------------------
Correct, we should not touch `get_file_info` when we have a list of paths.
> [Python][Dataset] Non-existent files are silently dropped in
> pa.dataset.FileSystemDataset

> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python

> Priority: Critical
> Labels: dataset
> Fix For: 1.0.0
>
>
> When passing a list of files to the constructor of
> {{pyarrow.dataset.FileSystemDataset}}, all files that don't exist are
> silently dropped immediately (i.e. no fragments are created for them).
> Instead, I would expect that fragments will be created for them but an error
> is thrown when one tries to read the fragment with the non-existent file.
