Hi, I've been trying to track down some problems with Spark reads being very slow with s3n:// URIs (NativeS3FileSystem). After some digging around, I realized that this file system implementation fetches the entire file, which isn't really a Spark problem, but it really slows down things when trying to just read headers from a Parquet file or just creating partitions in the RDD. Is this something that others have observed before, or am I doing something wrong?
Thanks, Akshat
