-------------------------------------
This makes perfect sense. I'd like to take this.
> Show "Warn - received late message for checkpoint" only when checkpoint
> actually expired

> Key: FLINK-15922
> URL: https://issues.apache.org/jira/browse/FLINK-15922
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Checkpointing
> Affects Versions: 1.10.0
> Reporter: Stephan Ewen
> Priority: Not a Priority
> Labels: auto-deprioritized-major, beginner, beginner-friendly,
> usability
>
> The message "Warn - received late message for checkpoint" is shown frequently
> in the logs, also when a checkpoint was purposefully canceled.
> In those case, this message is unhelpful and misleading.
> We should log this only when the checkpoint is actually expired.
> Meaning that when receiving the message, we check if we have an expired
> checkpoint for that ID. If yes, we log that message, if not, we simply drop
> the message.
