[jira] [Created] (SAMZA-1147) ZkJobCoordinator does not honor the interface contract of JobCoordinator

Navina Ramesh created SAMZA-1147:
------------------------------------

             Summary: ZkJobCoordinator does not honor the interface contract of JobCoordinator
                 Key: SAMZA-1147
                 URL: https://issues.apache.org/jira/browse/SAMZA-1147
             Project: Samza
          Issue Type: Bug
            Reporter: Navina Ramesh
            Assignee: Navina Ramesh
            Priority: Critical


There is a mismatch in how StandaloneJobCoordinator and ZkJobCoordinator handle the start/stop/awaitStart semantics of JobCoordinator. 
This impacts the StreamProcessor API behavior as well since the guarantees on the semantics of start / stop of the processors are broken in different runtime environments. This is weird and we need to revisit the how the components interact - StreamProcessor, JobCoordinator and SamzaContainer.
