> Pre HADOOP-3150, if the job fails in the init stage, {{job.kill()}} was
> called. This used to make sure that the job was cleaned up w.r.t
> - staus set to KILLED/FAILED
> - job files from the system dir are deleted
> - closing of job history files
> - making jobtracker aware of this through {{jobTracker.finalizeJob()}}
> - cleaning up the data structures via {{JobInProgress.garbageCollect()}}
> Now if the job fails in the init stage, {{job.fail()}} is called which doesnt
> do the cleanup. HADOOP-3150 introduces cleanup tasks which are launched once
> the job completes i.e killed/failed/succeeded. Jobtracker will never
> consider this job for scheduling as the job will be in the {{PREP}} state
> forever.
