--------------------------------

             Summary: Remove need to copy over all events from attempt 1 to 
attempt 2 dir
                 Key: TEZ-1909
                 URL: https://issues.apache.org/jira/browse/TEZ-1909
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Hitesh Shah


Use of file versions should prevent the need for copying over data into a 
second attempt dir. Care needs to be taken to handle "last corrupt record" 
handling.
