    Description

      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.
