David Christle commented on FLINK-32212:
----------------------------------------
We also see this issue. In one case, the logs appear to show k8s scaling down
the node containing the JobManager. When it restarts, it tries to redeploy the
Flink application, but endlessly retries with "The library registration
references a different set of library BLOBs" error.
> Job restarting indefinitely after an IllegalStateException from
> BlobLibraryCacheManager

> 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:
> java.lang.IllegalStateException: The library registration references a
