----------------------------------

[~pnowojski] What do you think of this problem?
I could take this ticket as I also need to change the exception handling part of code for {{notifyCheckpointAborted}} on task side.

> FLINK-17350 let the task fail immediately once sync phase of checkpoint failed. However, the included commit ['Simplify checkpoint exception handling'|https://github.com/apache/flink/pull/12101/commits/a2cd3daceca16ae841119d94a24328b4af37dcd8] actually would not fail the task if the runnable of {{() -> notifyCheckpointComplete}} throwing exception out.
> In a nutshell, this actually changes previous checkpoint exception handling.
> Moreover, that part of code also affect the implemented code of {{notifyCheckpointAbortAsync}} when I introduce {{notifyCheckpointAborted}} on task side.
