-------------------------------
Summary: 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
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)
