> {{RecoveryManager.recover()}} can throw an exception while recovering a job. 
> Since the {{JobTracker}} calls {{RecoveryManager.recover()}} from 
> {{offerService()}}, any failure in recovery will cause {{JobTracker}} to 
> crash. Ideally the {{RecoveryManager}} should log the failure encountered 
> while recovering the job and continue.
