> Currently reading parquet files generated by Hadoop (EMR) from S3 fails with "ValueError: Found files in an intermediate directory" because of the [_$folder$|http://stackoverflow.com/questions/42876195/avoid-creation-of-folder-keys-in-s3-with-hadoop-emr] empty files. 
> The fix should be easy, just an extra condition in [ParquetManifest._should_silently_exclude|https://github.com/apache/arrow/blob/master/python/pyarrow/parquet.py#L770].
