             Summary: make sure that a new job model will be generated if zk barrier times out.
                 Key: SAMZA-1368
                 URL: https://issues.apache.org/jira/browse/SAMZA-1368
             Project: Samza
          Issue Type: Bug
            Reporter: Boris Shkolnik
            Assignee: Boris Shkolnik


When barrier times out, participants do nothing. We rely on fact that the timeout happened because of a participant leaving. But if it timed out for any other reason, we may end up in a stuck state. 
So to cover this unknown we will add an explicit call to doOnProcessorChange for the leader.
