[jira] [Created] (SAMZA-1201) Zk path setup for leader elector and barrier should be separated

--------------------------------

             Summary: Zk path setup for leader elector and barrier should be separated
                 Key: SAMZA-1201
                 URL: https://issues.apache.org/jira/browse/SAMZA-1201
             Project: Samza
          Issue Type: Bug
            Reporter: Xinyu Liu
            Assignee: Boris Shkolnik


Right now all the zk paths are created inside ZkControllerImpl.init(). However, this doesn't work for coordinator service which uses ZkLeaderElector but not ZkControllerImpl. The creation of these paths needs to separated so that:

* ZkLeaderElector ensures the processor paths exist
* ZkBarrierForVersionUpdate ensures the job model version paths exist

This way they can be used independently.
