> 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.
