Looks good. The only thing is we checked in binary files directly. It would
be hard to maintain in the future. Can you generate the parquet file using the
parquetwriter?

> There is a long history about the LZ4 interoperability of parquet files
> between parquet-mr and parquet-cpp (which is now in the Apache Arrow).
> Attached links are the evidence. In short, a new LZ4_RAW codec type has been
> introduced since parquet format v2.9.0. However, only parquet-cpp supports
> LZ4_RAW. The parquet-mr library still uses the old Hadoop-provided LZ4 codec
> and cannot read parquet files with LZ4_RAW.
