I think this is good.
Few comments inline on the names, the hardest problem usually ;-)
> Replace ActorGateway in Task by interface
> -----------------------------------------
>
> Key: FLINK-4456
> URL: https://issues.apache.org/jira/browse/FLINK-4456
> Project: Flink
> Issue Type: Improvement
> Components: TaskManager
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
>
> The {{Task}} communicates with the outside world ({{JobManager}} and
> {{TaskManager}}) via {{ActorGateways}}. This bakes in the dependency on
> actors.
> In terms of modularization and an improved abstraction (especially wrt
> Flip-6) I propose to replace the {{ActorGateways}} by interfaces which
> exposes the required methods. The current implementation would then simply
> wrap the method calls in messages and send them via the {{ActorGateway}} to
> the recipient.
> In Flip-6 the {{JobMaster}} could simply implement these interfaces as part
> of their RPC contract.
