[jira] [Created] (REEF-560) Add a configurable timeout for driver to recover evaluators on restart

---------------------------------

             Summary: Add a configurable timeout for driver to recover evaluators on restart
                 Key: REEF-560
                 URL: https://issues.apache.org/jira/browse/REEF-560
             Project: REEF
          Issue Type: Sub-task
          Components: REEF Driver
            Reporter: Andrew Chung


Currently on restart, if we fail to recover an evaluator, we generate a FailedEvaluatorEvent. If the user does not request for new evaluators on restart and no active evaluator has reported back to it yet before we fire the FailedEvaluatorEvent, the clock will detect idle and terminate the AM. There should be a configurable timeout such that we allow the driver to be idle for the time being and wait for active tasks to report back to it.
