[jira] [Created] (FLINK-26750) HA cluster cleanup not complete

Matthias Pohl created FLINK-26750:
-------------------------------------

             Summary: HA cluster cleanup not complete
                 Key: FLINK-26750
                 URL: https://issues.apache.org/jira/browse/FLINK-26750
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.14.4, 1.15.0
            Reporter: Matthias Pohl


When starting a Flink cluster with HA (tested with ZooKeeper) in standalone mode and stopping it right away (i.e. {{./bin/start-cluster.sh; ./bin/stop-cluster.sh}}), the paths are not properly cleaned:
{code}
$ ls -R /
/
/flink
/zookeeper
/flink/default
/flink/default/jobgraphs
/flink/default/leader
/zookeeper/config
/zookeeper/quota
{code}

The {{/flink}} path should not be present when stopping the cluster.

This is most likely also a problem in k8s HA. That should be checked as part of this ticket.
