             Summary: Remove task commit burden from user code
                 Key: TEZ-694
                 URL: https://issues.apache.org/jira/browse/TEZ-694
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Bikas Saha


Its easy to forget to add commit logic in the processor after the logic in the run() method is done. After that its hard to debug why the outputs are not appearing after the dag completes even though all the tasks have been completed successfully. Since commit is an operation that should happen after the processor completes, it cannot be delegated entirely to the outputs. We can either do it in the LIORuntimeTask after processor.run() completes or create and abstract base processor class that does this after the real run() method completes.
