[jira] [Created] (REEF-1548) DriverStatusManager interface is not coherent

Sergiy Matusevych created REEF-1548:
---------------------------------------

             Summary: DriverStatusManager interface is not coherent
                 Key: REEF-1548
                 URL: https://issues.apache.org/jira/browse/REEF-1548
             Project: REEF
          Issue Type: Improvement
          Components: REEF Driver
            Reporter: Sergiy Matusevych
            Assignee: Sergiy Matusevych
            Priority: Minor


Class {{DriverStatusManager}} manages the driver state and provides interface for state transitions, with methods like {{.onInit()}}, {{.onRunning()}}, {{.onError()}}, and such.

In addition to that, it also has a method {{.sendJobEndingMessageToClient()}} that currently has nothing to do with the dirver's state transitions. That is, in some parts of REEF we use {{DriverStatusManager}} solely as the proxy to the job client.

That duality in the class interface is not desirable, and I suspect that we can make the {{.sendJobEndingMessageToClient()}} method private and connect it to some driver state transition
