Joris Van den Bossche commented on ARROW-8283:
----------------------------------------------
[~npr] I am not fully sure it is a duplicate. At least from the higher level
picture, the other talks about _discovery_ (in which case you shouldn't end up
with non-existing paths) while this issue about when manually creating a
dataset of a list of paths. The fix might still be related though

> Key: ARROW-8283
> URL: https://issues.apache.org/jira/browse/ARROW-8283
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++ - Dataset, Python
> Reporter: Uwe Korn
> Priority: Major
>
> 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.
