> 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]

> The fix should be easy, just an extra condition in
