Examples of org.apache.helix.HelixManager.disconnect()

org.apache.helix.HelixManager.disconnect()
Disconnect from the cluster. All the listeners will be removed and disconnected from the server. Its important for the client to ensure that new manager instance is used when it wants to connect again.

      // {
      // manager.disconnect();
      // }
    } finally {
      if (manager != null) {
        manager.disconnect();
      }
    }
