Hi, Would like to kindly confirm my observation,
We use parquet-mr (java) to generate parquet file with LZ4 compression. To do this we have to compile/install hadoop native library with provides LZ4 codec. However, the generated parquet file, is not recognizable by parquet-cpp. I encountered following error when using the `tools/parquet_reader` binary, ``` Parquet error: Arrow error: IOError: Corrupt Lz4 compressed data. ``` Further search online get me to this JIRA ticket: https://issues.apache.org/jira/browse/HADOOP-12990 So, since hadoop LZ4 is incompatible with open source, parquet-mr lz4 is not compatible with parquet-cpp? Thanks, -- Alex Wang, Open vSwitch developer
