------------------------------------------------------------------
Hi [~adrianalexvasiliu], I think the underlying problem of this issue was that
the bucket lifecycle policy deleted files after 7 days. Hence, the problem was
not caused by Flink.
Your problem sounds a bit different. Maybe it is related to what kind of
guarantees the ReadWriteMany PV using rook-cephfs gives you. But it could also
be a Flink problem. What I would suggest is to open a new tickets and to
provide the debug logs of the Flink cluster that could not recover. Also it
would be interesting to know if you can reproduce the problem with the latest
Flink version.

> Project: Flink
> Issue Type: Bug
> Components: Deployment / Kubernetes
> Affects Versions: 1.11.3, 1.12.2, 1.13.0
> Reporter: Mikalai Lushchytski
> Priority: Major
> Labels: k8s-ha, pull-request-available

>
> After the JobManager pod failed and the new one started, it was not able to
> recover jobs due to the absence of recovery data in storage - config map
> pointed at not existing file.
>
> Due to this the JobManager pod entered into the `CrashLoopBackOff`state and
> was not able to recover - each attempt failed with the same error so the
> whole cluster became unrecoverable and not operating.
>
> I had to manually delete the config map and start the jobs again without the
> save point.
>
> If I tried to emulate the failure further by deleting job manager pod
> manually, the new pod every time recovered well and issue was not
> reproducible anymore artificially.
