      • jmPodNeverStarted

        public static boolean jmPodNeverStarted​(io.javaoperatorsdk.operator.api.reconciler.Context<?> context)
        Check if the jobmanager pod has never successfully started. This is an important check to determine whether it is possible that the job has started and taken any checkpoints that we are unaware of.

        The way we check this is by using the availability condition transition timestamp. If the deployment never transitioned out of the unavailable state, we can assume that the JM never started.

        参数:
        context - Resource context
        返回:
        True only if we are sure that the jobmanager pod never started
