Flink HA Cluster JobManager 问题
Flink HA Cluster JobManager issues
我有一个 flink 1.2 集群设置，由 3 个 JobManager 和 2 个 TaskManager 组成。我从 JobManager1 启动 Zookeeper Quorum，我得到确认 Zookeeper 在其他 2 个 JobManager 上启动，然后我在这个 JobManager1 上启动 Flink 作业。
flink-conf.yaml 在所有 5 个虚拟机上都是相同的，这意味着 jobmanager.rpc.address：到处都指向 JobManager1。
如果我关闭 VM 运行 JobManager1，我希望 Zookeeper 说剩余的 JobManager 之一是领导者，TaskManager 应该重新连接到它。相反，我在 TaskManagers 的日志中收到了很多这样的消息

为了保密，我将原始 IP 修改为 1.2.3.4，因为它始终是相同的 IP（JobManager1）。

有谁知道为什么 TaskManager 不尝试重新连接到剩余的 JobManager 之一（如上面的 1.2.3.5）？
谢谢！
对于面临相同问题的每个人，HA 要求您提供一个可从所有节点访问的 DFS 位置。我有后端状态检查点目录和 zookeeper 存储目录在每个 VM 上指向本地文件系统位置，当其中一个 JobManager 出现故障时，新领导无法恢复 运行 作业，因为缺少信息/位置无法访问.
编辑：由于有人提出这个问题，我修改的文件（在 Apache Flink 1.2 (https://ci.apache.org/projects/flink/flink-docs-release-1.2/setup/config.html) 的情况下）是
conf/flink-conf.yaml
我设置
state.backend.fs.checkpointdir
high-availability.zookeeper.storageDir
到 AWS S3 路径。可从 TaskManagers 和 JobManagers 访问。
我有一个 flink 1.2 集群设置，由 3 个 JobManager 和 2 个 TaskManager 组成。我从 JobManager1 启动 Zookeeper Quorum，我得到确认 Zookeeper 在其他 2 个 JobManager 上启动，然后我在这个 JobManager1 上启动 Flink 作业。
flink-conf.yaml 在所有 5 个虚拟机上都是相同的，这意味着 jobmanager.rpc.address：到处都指向 JobManager1。
如果我关闭 VM 运行 JobManager1，我希望 Zookeeper 说剩余的 JobManager 之一是领导者，TaskManager 应该重新连接到它。相反，我在 TaskManagers 的日志中收到了很多这样的消息

有谁知道为什么 TaskManager 不尝试重新连接到剩余的 JobManager 之一（如上面的 1.2.3.5）？
谢谢！
对于面临相同问题的每个人，HA 要求您提供一个可从所有节点访问的 DFS 位置。我有后端状态检查点目录和 zookeeper 存储目录在每个 VM 上指向本地文件系统位置，当其中一个 JobManager 出现故障时，新领导无法恢复 运行 作业，因为缺少信息/位置无法访问.
编辑：由于有人提出这个问题，我修改的文件（在 Apache Flink 1.2 (https://ci.apache.org/projects/flink/flink-docs-release-1.2/setup/config.html) 的情况下）是
conf/flink-conf.yaml
我设置
state.backend.fs.checkpointdir
high-availability.zookeeper.storageDir
到 AWS S3 路径。可从 TaskManagers 和 JobManagers 访问。
