Flink Jira Bot updated FLINK-22060:
-----------------------------------
Labels: auto-deprioritized-major stale-minor (was:
auto-deprioritized-major)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Move null handling from ErrorInfo into Task.notifyFinalState

> Key: FLINK-22060
> URL: https://issues.apache.org/jira/browse/FLINK-22060
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.11.3, 1.12.2, 1.13.0
> Reporter: Matthias
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor

> Ideally, we would want to have this {{null}} check since a failure should
> always have a cause. We didn't introduce a null check so far because of
> FLINK-21376. There is [ErrorInfo.
> createErrorInfoWithNullableCause|https://github.com/apache/flink/blob/c77a686c195d1742c276f4a9e75899c8b85377bb/flink-runtime/src/main/java/org/apache/flink/runtime/executiongraph/ErrorInfo.java#L50]
> for handling this. But it feels to be handled in the wrong place. Instead,
> we should substitute the {{null}} value by the {{FlinkException}} in
> [Task.notifyFinalState|https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/taskmanager/Task.java#L1003].
> This way, we make sure that {{null}} never ends up in the
> {{ExecutionGraph}}-related code which enables us to make the invariants
> stricter on our end.
> This would serve as a preparation task
