-----------------------------------
Labels: pull-request-available (was: )
> Race condition between task/savepoint notification failure
> ----------------------------------------------------------
>
> Key: FLINK-27972
> URL: https://issues.apache.org/jira/browse/FLINK-27972
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.15.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
>
> When a task throws an exception in notifyCheckpointComplete we send 2
> messages to the JobManager:
> 1) we inform the CheckpointCoordinator about the failed savepoint
> 2) we inform the scheduler about the failed task.
> Depending on how these arrive the adaptive scheduler exhibits different
> behaviors. If 1) arrives first it properly informs the user about the created
> savepoint which might contain uncommitted transactions; if 2) arrives first
> it just restarts the job.
> I'm not sure how big of an issue the latter case is, but it does invalidate
> FLINK-26923.
> In any case we might want to consider having the StopWithSavepoint state wait
> until the savepoint future has failed before doing anything else.
