             Summary: Remove job lifecycle methods from public JobMasterGateway interface
                 Key: FLINK-7489
                 URL: https://issues.apache.org/jira/browse/FLINK-7489
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.4.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
            Priority: Minor


The {{JobMaster}} exposes its job lifecycle methods {{startJobExecution}} and {{suspendExecution}} via its {{JobMasterGateway}} to the public. I think these methods should not be exposed because it allows other components to affect the job execution without proper reason. Only the {{JobManagerRunner}} should be responsible for calling these methods and has direct access to the {{JobMaster}} instance. Therefore, these methods can directly be implemented by the {{JobMaster}} without exposing them via the {{JobMasterGateway}}.
