Flink Jira Bot updated FLINK-13695:
-----------------------------------
Priority: Major (was: Critical)
> Integrate checkpoint notifications into StreamTask's lifecycle
> --------------------------------------------------------------
>
> Key: FLINK-13695
> URL: https://issues.apache.org/jira/browse/FLINK-13695
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.9.0, 1.10.0
> Reporter: Till Rohrmann
> Priority: Major
> Labels: auto-deprioritized-critical
>
> The {{StreamTask's}} asynchronous checkpoint notifications are decoupled from
> the {{StreamTask's}} lifecycle. Consequently, it can happen that a
> {{StreamTask}} is terminating/cancelling and still sends asynchronous
> checkpoint notifications (e.g. acknowledge/decline checkpoint notifications).
> This is problematic because a cancelling/terminating {{StreamTask}} might
> cause an asynchronous checkpoint to fail which is expected and should not be
> reported to the {{JobMaster}}.
> Hence, the checkpoint notifications should be coupled with the
> {{StreamTask's}} lifecycle (e.g. notifications must be sent from the
> {{StreamTask's}} main thread) and if not valid, then they need to be filtered
> out/suppressed.
