【问题描述】：
我正在尝试设置由 2 个主节点和一个工作节点组成的 Apache Flink 独立集群。使用 Flink 1.6 和 Zookeeper。为了启动和停止集群，我使用了 Flink 1.6 文档中描述的过程，即启动集群我运行 start-zookeeper-quorum.sh 然后 start-cluster.sh 为了停止集群，我运行了 stop-cluster.sh
在运行一个作业（失败）后，然后再次停止并重新启动集群，我注意到两个作业管理器都无法启动的错误，因为他们正在寻找不存在的目录 job_e44fdee88a931200953fed45883ee3f1（我假设这是我的目录工作失败，但不确定）
如何从这个错误中恢复集群？

感谢您的回复，直到。我有几个新问题。这个特定的错误是否仅适用于独立的 HA 集群实现，或者它也存在于 Yarn 和 Kubernetes HA 设置中？修复的预计发布日期是什么（如果你有的话）同时我能做些什么来清除当前的 Flink 状态，使其停止寻找不存在的 blob 目录？
