Description

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.
