> LZO codec was removed in HADOOP-4874 because the original LZO binding is GPL which is problematic. However, many legacy data is still compressed by LZO codec, and companies often use vendor's GPL LZO codec in the classpath which might cause GPL contamination.
> Presro and ORC-77 use [aircompressor| [https://github.com/airlift/aircompressor]] (Apache V2 licensed) to compress and decompress LZO data. Hadoop can add back LZO support using aircompressor without GPL violation.
