Ability for having user's classes take precedence over the system classes for tasks' classpath

    Details

      Description

      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.
