[jira] [Created] (REEF-837) Stop using ErrorHandlerRID.NONE to mark "no client connected"

Mariia Mykhailova created REEF-837:
--------------------------------------

             Summary: Stop using ErrorHandlerRID.NONE to mark "no client connected"
                 Key: REEF-837
                 URL: https://issues.apache.org/jira/browse/REEF-837
             Project: REEF
          Issue Type: Improvement
            Reporter: Mariia Mykhailova


Currently we're using {{ErrorHandlerRID.NONE}} and {{ClientRemoteIdentifier.NONE}} to denote that a Driver doesn't have a persistent connection to the client. Whenever we need to differentiate behavior for "client" and "no client" scenarios, we compare id to NONE value. 

A proper approach would be to funnel all the communications to the client through an interface, and then bind proper implementation according to whether or not there is a client.
