Anurag Kyal commented on FLINK-32212:
-------------------------------------
I am running into this issue as well after my job restarts (trying to figure
out the reason for random restarts) but these errors show up. Most of the times
it stops after 8-10 exceptions but occasionally it gets into an infinite loop.
I am using a pubsub connector to read notifications as the first step in my job
and seems like these exceptions are related to this step - at least that is
what the UI says.
Was anyone able to find other solutions rather than manual intervention which I
want to avoid in the middle of night.

> Key: FLINK-32212
> URL: https://issues.apache.org/jira/browse/FLINK-32212
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.16.1
> Environment: Apache Flink Kubernetes Operator 1.4
> Reporter: Matheus Felisberto
> Priority: Major
>
> After running for a few hours the job starts to throw IllegalStateException
> and I can't figure out why. To restore the job, I need to manually delete the
> FlinkDeployment to be recreated and redeploy everything.
> The jar is built-in into the docker image, hence is defined accordingly with
> the Operator's documentation:
> {code:java}
> // jarURI: local:///opt/flink/usrlib/my-job.jar {code}
> I've tried to move it into /opt/flink/lib/my-job.jar but it didn't work
> either.

> switched from DEPLOYING to FAILED with failure cause:
