[jira] [Created] (FLINK-27572) Verify HA Metadata present before performint last-state restore

Gyula Fora created FLINK-27572:
----------------------------------

             Summary: Verify HA Metadata present before performint last-state restore
                 Key: FLINK-27572
                 URL: https://issues.apache.org/jira/browse/FLINK-27572
             Project: Flink
          Issue Type: Bug
          Components: Kubernetes Operator
            Reporter: Gyula Fora
             Fix For: kubernetes-operator-1.0.0


When we restore a job using the last-state logic we need to verify that the HA metadata has not been deleted. And if it's not there we need to simply throw an error because this requires manual user intervention.

This only applies when the FlinkDeployment is not already in a suspended state with recorded last state information.

The problem be reproduced easily in 1.14 by triggering a fatal job error. (turn of restart-strategy and kill TM for example). In these cases HA metadata will be removed, and the next last-state upgrade should throw an error instead of restoring from a completely empty state.
