>
> If a map task attempt is retroactively failed due to excessive fetch failures
> reported by reducers then the attempt's finish time is set to the time the
> task was retroactively failed rather than when the task attempt completed.
> This causes the map task attempt to appear to have run for much longer than
> it actually did.
