> Something tasks failed because of issues on NMs. For example, bad disk/network could
cause reducer fetching failure and mappers need to be re-scheduled.
> It will be very helpful to identify such issues if we could print host of failed tasks,
which we can simply grep MR AM's log to see what happened.
