Description

Hello , we just tried latest apache-arrow version 3.0.0 and the write example included in low level api example, but lz4 still seems not compatible with Hadoop . we got this error reading over hadoop file parquet produced with 3.0.0 library  :

 [leal@sulu parquet]$ ./hadoop-3.2.2/bin/hadoop jar apache-parquet-1.11.1/parquet-tools/target/parquet-tools-1.11.1.jar head --debug parquet_2_0_example2.parquet

any advice ? we need to write Lz4 files by C++ and read oover Hadoop jobs but still stuck on this problem .
