             Summary: Inconsistency in Kubernetes HA service: broken state handle
                 Key: FLINK-28265
                 URL: https://issues.apache.org/jira/browse/FLINK-28265
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.14.4
            Reporter: Robert Metzger


I have a JobManager, which at some point failed to acknowledge a checkpoint:

{code}
Error while processing AcknowledgeCheckpoint message
org.apache.flink.runtime.checkpoint.CheckpointException: Could not complete the pending checkpoint 193393. Failure reason: Failure to finalize checkpoint.

{code}

the JobManager creates subsequent checkpoints successfully.
Upon failure, it tries to recover this checkpoint (0000000000000193393), but fails to do so because of:
{code}
Caused by: org.apache.flink.util.FlinkException: Could not retrieve checkpoint 193393 from state handle under checkpointID-0000000000000193393. This indicates that the retrieved state handle is broken. Try cleaning the state handle store ... Caused by: java.io.FileNotFoundException: No such file or directory: s3://xxx/flink-ha/xxx/completedCheckpoint72e30229420c
{code}

I'm running Flink 1.14.4.
