-------------------------------------
Summary: Rethink SubmittedJobGraphListener
Key: FLINK-10344
URL: https://issues.apache.org/jira/browse/FLINK-10344
Project: Flink
Issue Type: Sub-task
Components: Distributed Coordination
Affects Versions: 1.6.0, 1.5.3, 1.7.0
Reporter: Till Rohrmann
Fix For: 1.7.0
The {{SubmittedJobGraphListener}} in {{ZooKeeperSubmittedJobGraphStore}} can
return false positives. This is obviously problematic, because it causes the
subsequent recovery operation to fail. Ideally we would not require the
{{SubmittedJobGraphListener}}. One could, for example, periodically check from
the main thread whether there are new jobs. That way we would know which jobs
are currently running and which are being cleaned up.
Alternatively it is necessary to tolerate false positives :-(
