JobManager не перенаправляет все запросы автоматически на оставшийся / работающий TaskManager

Описание проблемы

  1. 2 компьютера (203 204)
  2. создали автономный режим кластера HA Flink v1.6.1
  3. и запустите диспетчер заданий и диспетчер задач (2 слота задач) на каждом компьютере
  4. После того, как я запускаю задание (примеры SocketWindowWordCount.jar ./flink run ../examples/streaming/SocketWindowWordCount.jar --hostname 10.1.2.9 --port 9000) на узле JobManager, я убиваю работающий экземпляр TaskManager.
  5. Веб-панель управления. Я вижу, что задание отменено, а затем не выполнено. Изображение веб-панели управления

Журналы показывают, что ваш RestartStrategy исчерпал свои попытки перезапуска или что RestartStrategy не было настроено.Пожалуйста, проверьте, указали ли вы RestartStrategy в вашей программе через env.setRestartStrategy(RestartStrategies.fixedDelayRestart(10, 0L)) или flink-conf.yaml через restart-strategy: fixed-delay.Если вы хотите узнать больше о стратегиях перезапуска Flink, ознакомьтесь с документацией .
