无法使用Zookeeper启动Flink HA群集

Question

我试图安装一个Flink HA群集（动物园管理员模式），但任务管理器找不到作业管理器。

这里我给你介绍一下建筑；

- Machine 1 : Job Manager + Zookeeper
- Machine 2 : Task Manager

大师：

Machine1

奴隶：

Machine2

flink-conf.yaml：

#jobmanager.rpc.address: localhost
jobmanager.rpc.port: 6123
blob.server.port: 50100-50200
taskmanager.data.port: 6121
high-availability: zookeeper
high-availability.zookeeper.quorum: Machine1:2181
high-availability.zookeeper.path.root: /flink-1.5.1
high-availability.cluster-id: /default_b
high-availability.storageDir: file:///shareflink/recovery

这里是任务管理器的日志，它试图连接到localhost而不是Machine1：

PS.：/etc/hosts包含localhost、Machine1和Machine2

你能告诉我任务经理如何连接到工作经理吗？

当做

Answer 1

这就是我们对TaskManager的看法。它是否可以作为一个没有HA的集群工作？

root@flink-taskmanager-deployment-nonprod-597f858cb-4nmbr:/opt/flink# cat conf/masters 
flink-jobmanager-nonprod.rpds.svc.cluster.local:8081

root@flink-taskmanager-deployment-nonprod-597f858cb-4nmbr:/opt/flink# cat conf/slaves 
localhost

root@flink-taskmanager-deployment-nonprod-597f858cb-4nmbr:/opt/flink# cat conf/flink-conf.yaml 

jobmanager.rpc.address: flink-jobmanager-nonprod.rpds.svc.cluster.local
