vinoyang commented on FLINK-12514:
----------------------------------

[~pnowojski] I will give a more detailed description. I said this is a 
refactor, because I have implemented a simple counting mechanism based on 
{{AtomicInteger}}. The context of this idea comes from the PR of FLINK-12364, 
Stefan proposed it.

Whatever, I totally agree with your comment. And rework the title and 
description.

> Currently, the checkpoint failure manager uses a simple counting mechanism 
> which does not tract checkpoint id sequence.
> However, a more graceful counting mechanism is based on ordered checkpoint id 
> sequence.
> It should be refactored after the FLINK-12364 would been merged.
