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

             Summary: Issues with the count of failed/killed tasks in the jhist file
                 Key: MAPREDUCE-6892
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6892
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client, jobhistoryserver
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko


Recently we encountered some issues with the value of failed tasks. After parsing the jhist
file, {{JobInfo.getFailedMaps()}} returned 0, but actually there were failures. 

Another minor thing is that you cannot get the number of killed tasks (although this can be
calculated).

The root cause is that {{JobUnsuccessfulCompletionEvent}} contains only the successful map/reduce
task counts. Number of failed (or killed) tasks are not stored.
