Running tasks on lost trackers are incorrectly logging the attempt and task failures
------------------------------------------------------------------------------------

                 Key: HADOOP-5282
                 URL: https://issues.apache.org/jira/browse/HADOOP-5282
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Amar Kamat
            Priority: Blocker
             Fix For: 0.21.0


If a running attempt is lost on a tracker, a attempt-level cleanup with the same attempt-id
is launched for it. In such cases the events are not logged correctly and instead of logging
{code}
Task Reduce Start
Attempt Reduce Start
Attempt Reduce Killed 
Task reduce Killed
{code}
it logs
{code}
Task Reduce Start
Task Reduce Failed
Attempt Reduce Start
Attempt Reduce Killed 
{code}
