             Summary: Flink JobManager failed to restart in K8S HA setup
                 Key: FLINK-21685
                 URL: https://issues.apache.org/jira/browse/FLINK-21685
             Project: Flink
          Issue Type: Bug
          Components: Deployment / Kubernetes
    Affects Versions: 1.12.2, 1.12.1
            Reporter: Peng Zhang
         Attachments: flink-ha.log

We use Flink K8S session cluster with HA mode (1 JobManager and 4 TaskManagers). When jobs are running in Flink, and JobManager restarted, Flink JobManager failed to recover job from checkpoint

Hello, looking at your error, it should be that the file could not be found, or there was a communication problem. Let me ask if your flink on k8s uses the StatefulSet mode? Or can you find the location of ck storage now?
