Release Note:
Fixes NPE and makes Gridmix simulate succeeded-jobs-with-failed-tasks. All tasks of such simulated jobs(including the failed ones of original job) will succeed.

Description

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.
