    @yanghua Thanks for your contribution but I am afraid to tell you that we have changed
our mind and decided that it is better not to allow checkpoints between the savepoint and
job cancelation.
    
    #5622 already implements this.

savepointDirectory)}}.
> by either taking a savepoint and cancel the job separately, or by migrating the logic
in {{JobCancellationWithSavepointHandlers}}. The former will have different semantics because
the checkpoint scheduler is not stopped. Thus it is not guaranteed that there won't be additional
checkpoints between the savepoint and the job cancelation.
