   @steveloughran +1 on tools/hadoop-compression, and we will work on it. 
   Since https://github.com/apache/hadoop/pull/2297 is almost ready to merge, is it okay we
merge it first, and work on creating `tools/hadoop-compression`?

> 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.
