I am trying to install a Flink HA cluster (Zookeeper mode) but the task
manager cannot find the job manager.
Here I give you the architecture;
- Machine 1 : Job Manager + Zookeeper
- Machine 2 : Task Manager
masters:
Machine1
slaves :
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
Here this is the log of Task Manager, it tries to connect to localhost
instead of Machine1:

PS. : **/etc/hosts** contains the **localhost, Machine1 and Machine2**
Can you please tell me how the Task Manager can connect to Job Manager ?
