> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Affects Versions: 1.2
> Reporter: Steven Zhang
> Priority: Major
> Labels: pull-request-available
>
> I started up a Standalone session Flink cluster and ran one job on it. I
> checked the configMaps and see the HA data.
>
> {code:java}
> kubectl get configmaps -n flink-operator
> NAME
> DATA AGE
> flink-config-sql-example-deployment-s3-testing
> 2 5m41s
> flink-operator-config
> 3 42h
> kube-root-ca.crt
> 1 42h
> sql-example-deployment-s3-testing-000000003f57cd5f0000000000000002-config-map
> 0 11m
> sql-example-deploymnt-s3-testing-cluster-config-map
> 5 12m
> {code}
>
> I then update the FlinkDep image field and the Flink cluster gets restarted.
> The HA configmap for the job is now gone.
> {code:java}

> kube-root-ca.crt 1 43h

>
> I think this is due to a race condition where the TM first terminates which
> causes the JM to interpret the Job entering a failed state which causes it to
> clean up the configmaps.
