> [R] Ignore "*_$folder$" files on S3 in {arrow} R package
> --------------------------------------------------------
>
> Key: ARROW-15280
> URL: https://issues.apache.org/jira/browse/ARROW-15280
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Affects Versions: 6.0.1
> Reporter: Bob Rudis
> Priority: Minor
>
> ARROW-4406 notes that:
> >Currently reading parquet files generated by Hadoop (EMR) from S3 fails with
> >"ValueError: >Found files in an intermediate directory" because of the
> >_$folder$ empty files.
> This was fixed in the pyarrow but R still has this issue.
> The R side does not seem to have something similar to:
> {{ def _should_silently_exclude(self, file_name):}}
> {{ return (file_name.endswith('.crc') or # Checksums}}
> {{ file_name.endswith('_$folder$') or # HDFS directories in S3}}
> {{ file_name.startswith('.') or # Hidden files starting with .}}
> {{ file_name.startswith('_') or # Hidden files starting with _}}
> {{ file_name in EXCLUDED_PARQUET_PATHS)}}
