Subject: Duplicate INIT in Controller
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit

Hi,

I am observing duplicate handlers being added to the controller and this 
is leading to INIT being called multiple times on the same handlers.

Here is my code to start the controler, which looks fairly standard:

     @Override
     protected void doStart() throws SystemException {
         hManager = HelixManagerFactory.getZKHelixManager(clusterName, 
UUID.randomUUID().toString(),
                 InstanceType.CONTROLLER, zkAddr);
         try {
             hManager.connect();
         } catch (Exception e) {
             throw new SystemException(e);
         }
         GenericHelixController controller = new GenericHelixController();
         HelixControllerMain.addListenersToController(hManager, controller);
     }


Here are the log messages due to duplicate calls:
