-------------------------------------
Hi Govind. What performance difference have you measured here?
> Native-code implementation of bzip2 codec
> -----------------------------------------
>
> Key: HADOOP-8462
> URL: https://issues.apache.org/jira/browse/HADOOP-8462
> Project: Hadoop Common
> Issue Type: Improvement
> Components: io
> Affects Versions: 0.23.1
> Reporter: Govind Kamat
> Original Estimate: 672h
> Remaining Estimate: 672h
>
> The bzip2 codec supplied with Hadoop is currently available only as a Java
> implementation. A version that uses the system bzip2 library can provide
> improved performance and a better memory footprint. This will also make it
> feasible to utilize alternative bzip2 libraries that may perform better for
> specific jobs.
