------------------------------------------

             Summary: Recovery reconciliation loop fails if no checkpoint has been created yet
                 Key: FLINK-30266
                 URL: https://issues.apache.org/jira/browse/FLINK-30266
             Project: Flink
          Issue Type: Bug
          Components: Kubernetes Operator
    Affects Versions: kubernetes-operator-1.3.0
            Reporter: Maximilian Michels
            Assignee: Gyula Fora


When the upgradeMode is LAST-STATE, the operator fails to reconcile a failed application unless at least one checkpoint has already been created. The expected behavior would be that the job starts with empty state.
