Description

If evaluator fails before task is submitted, EvaluatorManager.onResourceLaunch will find evaluator in failed state and throw a runtime exception reporting unexpected state. But in this case FailedEvaluator event should have already been generated (when evaluator state was set to failed), and the exception is not needed. We need to fix the code to not throw exception.
