> In a trace file, if a succeeded job contains a failed task, then that task's
> taskStatus will be null. This is causing NPE in Gridmix and then Gridmix is
> ignoring/not-considering such jobs for simulation. The job could succeed even
> with failed tasks if the job submitter in original cluster configured that
> job to tolerate failures using mapreduce.map.failures.maxpercent and
> mapreduce.reduce.failures.maxpercent.
