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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
