             Summary: The elapsed time for tasks in a failed job that were never started can be way off. 
                 Key: MAPREDUCE-5797
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5797
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobhistoryserver, webapps
    Affects Versions: 0.23.9
            Reporter: Rushabh S Shah
            Assignee: Rushabh S Shah


The elapsed time for tasks in a failed job that were never
started can be way off.  It looks like we're marking the start time as the
beginning of the epoch (i.e.: start time = -1) but the finish time is when the
task was marked as failed when the whole job failed.  That causes the
calculated elapsed time of the task to be a ridiculous number of hours.

Tasks that fail without any attempts shouldn't have start/finish/elapsed times.
