--------------------------------------
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.
