Andrea Peruffo commented on FLINK-22262:
----------------------------------------
Thanks for your input [~fly_in_gis] , I have incorporated most of your
suggestions in my repro:
[https://github.com/andreaTP/repro-FLINK-22262]
And I can still observe the same behavior:
after running "flink cancel" the JobManager Pod enters in something similar to
"CrashLoopBackoff" (keeps being restarted failing after some time) and the
relevant ConfigMaps are not removed.
Attached the full log of the JobManager that received the "cancel" command.

> Key: FLINK-22262
> URL: https://issues.apache.org/jira/browse/FLINK-22262
> Project: Flink
> Issue Type: Bug
> Components: Deployment / Kubernetes
> Affects Versions: 1.13.0
> Reporter: Andrea Peruffo
> Priority: Major
> Attachments: jm.log
>
>
> According to the documentation:
> [https://ci.apache.org/projects/flink/flink-docs-master/docs/deployment/resource-providers/native_kubernetes/#manual-resource-cleanup]
> 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}}
