> Key: FLINK-17672
> URL: https://issues.apache.org/jira/browse/FLINK-17672
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Priority: Critical
> Fix For: 1.11.0
>
>
> Currently, the OperatorCoordinators receive failure notifications on task
> restart. That follows the same approach as the InputSplit assigners from the
> legacy sources (after which the integration of the Coordinators with the
> Scheduler was modeled).
> However, propagating the failure notifications during the actual failure is
> more intuitive, and also improve situations where tasks fail but don't get
> restarted for a while (this can happen for batch tasks when a TM dies and no
> spare resources are available). In those cases, the coordinator can react
> much earlier to the failure.
