             Summary: Add configurable flag to disable last-state fallback for savepoint upgrade
                 Key: FLINK-28348
                 URL: https://issues.apache.org/jira/browse/FLINK-28348
             Project: Flink
          Issue Type: Improvement
          Components: Kubernetes Operator
            Reporter: Gyula Fora
             Fix For: kubernetes-operator-1.1.0


Currently if the job is not running and savepoint upgrade mode is configured, the ApplicationReconciler can fall back to last-state upgrade mode if HA was enabled.

While in most cases this is fine, in some situation the user might only want to allow savepoint ugrades. We should add a flag:



kubernetes.operator.job.upgrade.last-state-fallback.enabled : true

Default should be true to match the current behaviour.
