Till Rohrmann created FLINK-9456: ------------------------------------ Summary: 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 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
