> If the checkpoint is aborted, AsyncSnapshotCallable will close the
> snapshotCloseableRegistry when it is canceled. There may be two situations
> here:
> # The FSDataOutputStream has been created and closed while closing
> FsCheckpointStateOutputStream.
> # The FSDataOutputStream has not been created yet, but closed flag has been
> set to true. You can see this in log:

> {code}
> The output stream will be automatically closed by the
> SafetyNetCloseableRegistry but the file will not be deleted.
> The second case usually occurs when the storage system has high latency in
> creating files.
> How to reproduce?
> This is not easy to reproduce, but you can try to set a smaller checkpoint
> timeout and increase the parallelism of the flink job.
