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

             Summary: Replace ActorGateways in NetworkEnvironment by interfaces
                 Key: FLINK-4455
                 URL: https://issues.apache.org/jira/browse/FLINK-4455
             Project: Flink
          Issue Type: Improvement
          Components: Network, TaskManager
            Reporter: Till Rohrmann


The {{NetworkEnvironment}} communicates with the outside world ({{TaskManager}} and {{JobManager}})
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}} and the {{TaskExecutor}} could simply implement these interfaces
as part of their RPC contract.
