                 Key: MAPREDUCE-2506
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2506
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Owen O'Malley


In 0.21 we moved the org.apache.hadoop.mapreduce context objects to interfaces.

That made the APIs much better, but broke backwards compatibility for frameworks that need to clone them.
