------------------------------------

             Summary: Replace ActorGateway by TaskGateway interface
                 Key: FLINK-4887
                 URL: https://issues.apache.org/jira/browse/FLINK-4887
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Till Rohrmann
             Fix For: 1.2.0


Instead of accessing directly on the {{ActorGateway}} in the {{Execution}} and {{ExecutionVertex}} it would be better to decouple the two components by introducing the {{TaskGateway}} interface which provides access to task related rpc calls. The {{ActorGateway}} could be one implementation of the interface.

This change will prepare the further implementation of Flip-6.
