> Let ResourceManager notify JobManager about failed/killed TaskManagers
> ----------------------------------------------------------------------
>
> Key: FLINK-9456
> URL: https://issues.apache.org/jira/browse/FLINK-9456
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Coordination
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Assignee: Sihua Zhou
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.6.0, 1.5.1

>
> Often, the {{ResourceManager}} learns faster about TaskManager
> failures/killings because it directly communicates with the underlying
> resource management framework. Instead of only relying on the
> {{JobManager}}'s heartbeat to figure out that a {{TaskManager}} has died, we
> should additionally send a signal from the {{ResourceManager}} to the
> {{JobManager}} if a {{TaskManager}} has died. That way, we can react faster
> to {{TaskManager}} failures and recover our running job/s.
