So in 0.16 we plan to provide best effort readers, and aiming this ticket to
1.0.0, right?
> [C++][Dataset] Revisit File discovery failure mode
> --------------------------------------------------

> Key: ARROW-7673
> URL: https://issues.apache.org/jira/browse/ARROW-7673
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++ - Dataset
> Reporter: Francois Saint-Jacques
> Priority: Major
>
> Currently, the default `FileSystemFactoryOptions::exclude_invalid_files` will
> silently ignore unsupported files (either IO error, not of the valid format,
> corruption, missing compression codecs, etc...) when creating a
> `FileSystemSource`.
> We should change this behavior to propagate an error in the Inspect/Finish
> calls by default and allow the user to toggle `exclude_invalid_files`. The
> error should contain at least the file path and a decipherable error (if
> possible).
