> 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.
