Breaking out of a task
----------------------

                 Key: HADOOP-3973
                 URL: https://issues.apache.org/jira/browse/HADOOP-3973
             Project: Hadoop Core
          Issue Type: New Feature
            Reporter: Amir Youssefi


Occasionally a mapper/reducer is done without need to see more input data. If 
we provide a way to break out and skip reading the rest of input then job 
finishs earlier and resources are spared.
