> Key: FLINK-4457
> URL: https://issues.apache.org/jira/browse/FLINK-4457
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Coordination
> Reporter: Till Rohrmann
> Assignee: Stephan Ewen
> Fix For: 1.2.0
>
>
> Currently, the {{ExecutionGraph}} strongly depends on Akka as it requires an
> {{ActorSystem}} to create the {{CheckpointCoordinatorDeActivator}}.
> Furthermore, it allows {{ActorGateways}} to register for job status and
> execution updates.
> In order to improve modularization and abstraction I propose to introduce
> proper listener interfaces. This would also allow to get rid of the
> {{CheckpointCoordinatorDeActivator}} by simply implementing this interface.
> Furthermore it will pave the way for the upcoming Flip-6 refactoring as it
> offers a better abstraction.
