[jira] [Comment Edited] (FLINK-22262) Flink on Kubernetes ConfigMaps are created without OwnerReference

    [ https://issues.apache.org/jira/browse/FLINK-22262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17629585#comment-17629585 ]

------------------------------------------------------------

Thanks [~yunta] for sharing your problem. I think the root cause is finished job was submitted again unexpectedly.

If you want to completely ignore this issue, I suggest to use the job result store[1].

FYI: The Flink Kubernetes operator is also using the JRS to avoid duplicated submission.

Thanks [~yunta] for sharing your problem. I think the root cause might be kubelet is too late to know the deployment deletion. So the kubelet simply start the JobManager again exactly after it exited.

> The ConfigMaps created along with the Flink deployment is supposed to have an OwnerReference pointing to the Deployment itself, unfortunately, this doesn't happen and causes all sorts of issues when the classpath and the jars of the job are updated.
> i.e.:
> Without manually removing the ConfigMap of the Job I cannot update the Jars of the Job.
> Can you please give guidance if there are additional caveats on manually removing the ConfigMap? Any other workaround that can be used?
> Thanks in advance.
> Example ConfigMap:
> {{apiVersion: v1}}
> {{data:}}
> {{ address: akka.tcp://flink@10.0.2.13:6123/user/rpc/jobmanager_2}}
