------------------------------------

             Summary: Native implementation of java Checksum interface
                 Key: HADOOP-10859
                 URL: https://issues.apache.org/jira/browse/HADOOP-10859
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Minor


Some parts of our code such as IFileInputStream/IFileOutputStream use the java Checksum interface
to calculate/verify checksums. Currently we don't have a native implementation of these. For
CRC32C in particular, we can get a very big speedup with a native implementation.
