Thanks [~dbtsai] . This seems to be a good addition. I'll help reviewing the
PR. cc [~omalley] : would like to hear your opinion on this as well.
> Support LZO using aircompressor
> -------------------------------
>
> Key: HADOOP-17124
> URL: https://issues.apache.org/jira/browse/HADOOP-17124
> Project: Hadoop Common
> Issue Type: New Feature
> Components: common
> Affects Versions: 3.3.0
> Reporter: DB Tsai
> Priority: Major
>
> 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.
