[jira] [Created] (FLINK-26742) DefaultCompletedCheckpointStore.shutdown does not clean the checkpoints atomically

Matthias Pohl created FLINK-26742:
-------------------------------------

             Summary: DefaultCompletedCheckpointStore.shutdown does not clean the checkpoints atomically
                 Key: FLINK-26742
                 URL: https://issues.apache.org/jira/browse/FLINK-26742
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.15.0
            Reporter: Matthias Pohl


The {{DefaultCompletedCheckpointStore.shutdown}} removes the Checkpoint entry from the {{StateHandleStore}} and runs the actual cleanup of the checkpoint after it got removed. That means that the data is lost if there's an error while discarding the {{CompletedCheckpoint}} which, as a consequence, doesn't get picked up anymore during retry.
