Subject [jira] [Created] (ARROW-7061) [C++][Dataset] FileSystemDiscovery with ParquetFileFormat should ignore files that aren't Parquet

Neal Richardson created ARROW-7061:
--------------------------------------

             Summary: [C++][Dataset] FileSystemDiscovery with ParquetFileFormat should ignore
files that aren't Parquet
                 Key: ARROW-7061
                 URL: https://issues.apache.org/jira/browse/ARROW-7061
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++ - Dataset
            Reporter: Neal Richardson


I got {{Invalid parquet file. Corrupt footer.}} trying to read real data. Turned out it was
because I had opened the directory in macOS Finder and it had added the junk .DS_Store files.
Once I deleted them, the Dataset created fine. 

If we're creating a DataSource with Parquet files, we should ignore any non-Parquet files
we encounter when scanning.
