Resolution: Duplicate
> Residual zk data when using the kubernetes session mode
> -------------------------------------------------------
>
> Key: FLINK-30813
> URL: https://issues.apache.org/jira/browse/FLINK-30813
> Project: Flink
> Issue Type: Bug
> Components: Deployment / Kubernetes
> Reporter: liuzhuo
> Priority: Minor
>
> If we use kubernetes session mode and use Zookeeper(ZK) as the HA
> service, the HA data on ZK is not cleared after the session stops.
> Because when deleting a session, only call this method:
> {code:java}
> kubernetesClusterDescriptor.killCluster(clusterId);
> {code}
> However, this method only deletes the deployment associated with the
> clusterId. If ZK is used as the HA service, data on ZK will be left over when
> the HA stops, resulting in more and more data on zk.
>
> Maybe we need to add
> {code:java}
> ClusterClient#shutDownCluster(){code}
> or
> {code:java}
> HighAvailabilityServices#closeAndCleanupAllData(){code}
> When using session mode (native kubernetes)
