> Key: FLINK-10344
> URL: https://issues.apache.org/jira/browse/FLINK-10344
> Project: Flink
> Issue Type: Sub-task
> Components: Distributed Coordination
> Affects Versions: 1.5.3, 1.6.0, 1.7.0
> Reporter: Till Rohrmann
> Assignee: Shimin Yang
> Priority: Major
> 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 :-(
