ASF GitHub Bot commented on PARQUET-2196: ----------------------------------------- emkornfield commented on PR #1000: URL: https://github.com/apache/parquet-mr/pull/1000#issuecomment-1281847541 FWIW, Arrow/Parquet C++ checkout https://github.com/apache/parquet-testing when running parquet tests (instead of checking binary files into the main repo). As an aside, I think we do need better interop testing between parquet implementations, it wouldn't be trivial, but it would be really nice to have compatibility tests. > Support LZ4_RAW codec > --------------------- > > Key: PARQUET-2196 > URL: https://issues.apache.org/jira/browse/PARQUET-2196 > Project: Parquet > Issue Type: Improvement > Components: parquet-mr > Reporter: Gang Wu > Priority: Major > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
