Subject: Re: Kubernetes HA - attempting to restore from wrong (non-existing) savepointHi Alexey,
It seems that the KubernetesHAService works well since all the checkpoints have been cleaned up when the job is canceled.And we could find related logs "Found 0 checkpoints in KubernetesStateHandleStore{configMapName='gsp-00000000000000000000000000000000-jobmanager-leader'}.".
However, it is a little strange that the CheckpointCoordinator is recovering from a wrong savepoint path. Could you share thefull JobManager logs? One possible reason I could guess is the application cluster entrypoint is not creating a new JobGraph from the specified arguments.
Best,Yang

Hello,We have Flink job running in Kubernetes with Kuberenetes HA enabled (JM is deployed as Job, single TM as StatefulSet). We taken savepoint with cancel=true. Now when we are trying to start job using --fromSavepoint A, where is A path we got from taking savepoint (ClusterEntrypoint reports A in log), but looks like Job for some reason ignores given A and actually trying to restore from some path B (CheckpointCoordinator logs B ):
