                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1938
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: job submission, task, tasktracker
            Reporter: Devaraj Das
             Fix For: 0.22.0


It would be nice to have the ability in MapReduce to allow users to specify for their jobs
alternate implementations of classes that are already defined in the MapReduce libraries.
For example, an alternate implementation for CombineFileInputFormat.
