> 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.
