Looked at the code, it seems the nodeName is built as following, another question is that can I get this node name from JNDI or system variable somewhere? apart from the HaPartition service.

      public ClusterNode getClusterNode(Address a)
      {
         IpAddress result = addressMap.get(a);
         if (result == null)
         {
            result = (IpAddress) channel.downcall(new Event(Event.GET_PHYSICAL_ADDRESS, a));
            if (result == null)
            {
               throw new IllegalStateException("Address " + a + "not registered in transport layer");
            }
            addressMap.put(a, result);
         }
         AddressPort addrPort = new AddressPort(result.getIpAddress(), Integer.valueOf(result.getPort()));
         String id = channel.getName(a);
         if (id == null)
         {
            id = addrPort.getHostAddress() + ":" + addrPort.getPort();
         }
         return new ClusterNodeImpl(id, a, addrPort);
      }
   }
