我有一个装有Flink 1.2群集的设置，由3个Jobmanagers和2位Taskmanagers组成。我从JobManager1启动了Zookeeper Quorum，我从其他2个JobManagers开始确认Zookeeper，然后我在此JobManager1上开始了Flink Job。
flink-conf.yaml在所有5个VM上都是相同的，这意味着JobManager.rpc.rpc.address：指向jobmanager1无处不在。
如果我关闭了运行JobManager1的VM，我希望Zookeeper说剩下的一位Jobmanagers是领导者，任务管理人员应该重新连接它。取而代之的是，我进入了任务管理员的日志。

我将原始IP修改为1.2.3.4的机密性，并且因为它始终是相同的IP（JobManager1）。

有人知道为什么任务管理人员不试图重新连接到其余的求职者之一（例如上面的1.2.3.5）？
？谢谢！
对于面对同一问题的每个人，HA要求您提供可从所有节点访问的DFS位置。我有一个后端状态检查点目录和Zookeeper存储目录指向每个VM上的本地文件系统位置，当其中一位乔布管理人员下降时，新领导者无法恢复运行工作，因为缺乏信息/位置无法访问。p>编辑：由于询问了我修改的文件（如果是Apache Flink 1.2（https://ci.apache.org/projects/flink/flink/flink/flink/flink-docs-release-1.2/setup/config.html，html）是
conf/flink-conf.yaml
我设置
state.backend.fs.checkpointdir
high-availability.zookeeper.storageDir
到AWS S3路径。
