          void nodeConnected(String addr)

      Method is called on cluster node connection event. This is a notification to the component that a new cluster node has connected.
      Parameters:
        `addr` - is a hostname of a cluster node generating the event.

    - #### nodeDisconnected

          void nodeDisconnected(String addr)

      Method is called on cluster node disconnection event. This is a notification to the component that there was network connection lost to one of the cluster nodes.
      Parameters:
        `addr` - is a hostname of a cluster node generating the event.
