> 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.
