> {code}
> Cause of the issue is following:
> - We construct `jobMasterServices` prior starting `leaderElectionService` (in
> `JobManagerRunnerImpl`)
> - During `jobMasterServices` initialization
> `tryRestoreExecutionGraphFromSavepoint` gets called. This calls
> `KubernetesStateHandleStore.addAndLock` interally.
> - `KubernetesStateHandleStore.addAndLock` expects configmap for JM leadership
> to be already present, which is wrong, because `leaderElectionService` which
> is responsible for its creation has not started yet
> Possible fixes:
> - Start `leaderElectionService` before `jobMasterServices`
> - Fix `KubernetesStateHandleStore`, so it can handle the case, when leader
> hasn't been elected
