> 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.
