-----------------------------------------

             Summary: Flink TaskManager throws RegistrationTimeoutException when using Kubernetes HA
                 Key: FLINK-20982
                 URL: https://issues.apache.org/jira/browse/FLINK-20982
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.12.0
            Reporter: Levani Kokhreidze


I'm experimenting with Flink 1.12 release and testing out Kubernetes HA feature with Minikube. Unfortunately, when using Kubernetes HA, *TaskManager* can not register at *ResourceManager* and it throws *RegistrationTimeoutException* after 5min.


I can see that JobManager creates config maps with Kubernetes HA

 
{code:java}
➜ k get configmaps
NAME                                                          DATA   AGE
cluster1-00000000000000000000000000000000-jobmanager-leader   2      109s
cluster1-dispatcher-leader                                    4      2m
cluster1-resourcemanager-leader                               2      2m
cluster1-restserver-leader                                    2      2m
{code}
 

 

And when inspecting *{{cluster1-resourcemanager-leader}}* it seems to have correct value.
{code:java}

Connectivity from TaskManager pod also checks out.

The same setup, but with *zookeeper* HA works without any issues.

JobManager starts with  the following command:
{code:java}
exec "$FLINK_HOME"/bin/standalone-job.sh start-foreground "$@"
{code}
This is *ClusterRole* and *ClusterRoleBinding* that is granted to the namespace.
{code:java}
kubectl create clusterrole cr --verb="*" --resource=configmaps
