Levani Kokhreidze updated FLINK-20982:
--------------------------------------
Description:
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

> 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
> Priority: Major
>
> 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
