Я пытаюсь настроить автономный кластер Apache Flink, состоящий из 2 главных узлов и одного рабочего узла.Использование Flink 1.6 и Zookeeper.Для запуска и остановки кластера я использовал процесс, описанный в документации Флинка 1.6, то есть для запуска кластера я запустил start-zookeeper-quorum.sh, а затем start-cluster.sh, а для остановки кластера я запустил stop-cluster.sh
После запуска одного задания (которое не удалось), а затем снова остановив и перезапустив кластер, я заметил ошибку, при которой ни один из 2 менеджеров заданий не мог запуститься, потому что они ищут каталог job_e44fdee88a931200953fed45883ee3f1, который не существует (я предполагаю, что это каталог для моего сбойного задания, но не уверен)
Как восстановить кластер после этой ошибки?
