             Summary: 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
             Fix For: 0.23.3


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.
