[jira] [Created] (ARROW-7673) [C++][Dataset] Revisit File discovery failure mode

Francois Saint-Jacques created ARROW-7673:
---------------------------------------------

             Summary: [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


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).
