我试图让flink运行在ha模式下使用zookeeper,但当我试图通过杀死领队jobmanager来测试它时,我所有的备用jobmanager也会被杀死。
因此,他们都被杀了,而不是由一个待命的工作经理来接任新的领导,这是不应该发生的。
我的设置:4台服务器,其中3台运行zookeeper,但只有1台服务器将托管所有JobManager。
ad011.local: Zookeeper + Jobmanagers
ad012.local: Zookeeper + Taskmanager
ad013.local: Zookeeper
ad014.local: nothing interesting
我的masters文件如下所示:
ad011.local:8081
ad011.local:8082
ad011.local:8083
我的flink-conf.yaml:
jobmanager.rpc.address: ad011.local
blob.server.port: 6130,6131,6132
jobmanager.heap.mb: 512
taskmanager.heap.mb: 128
taskmanager.numberOfTaskSlots: 4
parallelism.default: 2
taskmanager.tmp.dirs: /var/flink/data
metrics.reporters: jmx
metrics.reporter.jmx.class: org.apache.flink.metrics.jmx.JMXReporter
metrics.reporter.jmx.port: 8789,8790,8791
high-availability: zookeeper
high-availability.zookeeper.quorum: ad011.local:2181,ad012.local:2181,ad013.local:2181
high-availability.zookeeper.path.root: /flink
high-availability.zookeeper.path.cluster-id: /cluster-one
high-availability.storageDir: /var/flink/recovery
high-availability.jobmanager.port: 50000,50001,50002
当我使用start-cluster.sh脚本运行flink时,我看到我的3个jobmanagers正在运行,它们都指向ad011。local:8081,这是领导者。我想这没关系吧?
然后,我尝试通过使用kill杀死领导者来测试故障转移,然后我的所有其他备用作业管理器也停止。
这是我在备用jobmanager日志中看到的:

任何帮助都将不胜感激。

解决方法是使用./bin/start-cluster.sh运行我的集群,而不是使用服务文件(调用相同的脚本),服务文件显然会杀死其他作业管理器。
