[~sihuazhou] agree with you, it's duplicate of FLINK-8871, I suggest we could 
close this issue and move to FLINK-8871.

> We should introduce an {{AbortCheckpoint}} message that a jobmanager can send 
> to taskmanagers if a checkpoint is canceled so that the operators can eagerly 
> stop their alignment phase and continue to normal processing. This can reduce 
> some backpressure issues in the context of canceled and restarted checkpoints.
