@steveloughran We are thinking the same. For example, if we add
`hadoop-compression` module, and move all the codecs such as `snappy`, `lz4`,
`gzip`, and `bzip` there, other projects such as Parquet can directly depend on
it without reimplementing their compression codec. Literally, many projects
reimplement the codec using the same interface which we will be able to avoid
by moving it into a separate module.

> 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
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
