Till Rohrmann commented on FLINK-22014:
---------------------------------------
[~fly_in_gis] I think the problem is that
{{AbstractHaServices.closeAndCleanupAllData}} calls
{{blobStoreService.closeAndCleanupAllData()}} which deletes the blobs from the
HA store (in our case S3). If the system now stops after this method has been
executed, then we keep the references in the ConfigMap/ZooKeeper but have no
longer the blobs available. This should be the problem [~mlushchytski]
experienced.

> Key: FLINK-22014
> URL: https://issues.apache.org/jira/browse/FLINK-22014
> Project: Flink
> Issue Type: Bug
> Components: Deployment / Kubernetes
> Affects Versions: 1.11.3, 1.12.2, 1.13.0
> Reporter: Mikalai Lushchytski
> Assignee: Till Rohrmann
> Priority: Critical
> Labels: k8s-ha, pull-request-available
> Fix For: 1.11.4, 1.13.0, 1.12.3
>
>
> 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.
