> Key: FLINK-8234
> URL: https://issues.apache.org/jira/browse/FLINK-8234
> Project: Flink
> Issue Type: Sub-task
> Components: Distributed Coordination
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Assignee: Gary Yao
> Labels: flip-6
> Fix For: 1.5.0
>
>
> In order to serve the {{JobExecutionResults}} we have to cache them in the
> {{Dispatcher}} after the {{JobManagerRunner}} has finished. The cache should
> have a configurable size and should periodically clean up stale entries in
> order to avoid memory leaks.
