> Add Brotli compression codec
> ----------------------------
>
> Key: HADOOP-13126
> URL: https://issues.apache.org/jira/browse/HADOOP-13126
> Project: Hadoop Common
> Issue Type: Improvement
> Components: io
> Affects Versions: 2.7.2
> Reporter: Ryan Blue
> Assignee: Ryan Blue
> Attachments: HADOOP-13126.1.patch, HADOOP-13126.2.patch,
> HADOOP-13126.3.patch
>
>
> I've been testing [Brotli|https://github.com/google/brotli/], a new
> compression library based on LZ77 from Google. Google's [brotli
> benchmarks|https://cran.r-project.org/web/packages/brotli/vignettes/brotli-2015-09-22.pdf]
> look really good and we're also seeing a significant improvement in
> compression size, compression speed, or both.
> {code:title=Brotli preliminary test results}
> [blue@work Downloads]$ time parquet from test.parquet -o test.snappy.parquet
> --compression-codec snappy --overwrite
> real 1m17.106s

> -rw-r--r-- 1 blue blue 2265950833 May 10 10:30 test.snappy.parquet
> {code}
> Brotli, at quality 1, is as fast as snappy and ends up smaller than gzip-9.
> Another test resulted in a slightly larger Brotli file than gzip produced,
> but Brotli was 4x faster. I'd like to get this compression codec into Hadoop.
