Configuring a two node hazelcast cluster - avoiding multicast

Question

The context

• Two nodes of a Hazelcast cluster, each on a discrete subnet so multicast is not suitable nor working for node location.

• I should like to employ the most minimal XML configuration file, say hazelcast.xml, to configure Hazelcast to use TCP/IP to connect the two nodes. Ideally a directory of the IP addresses of the two nodes.

The question

The Hazelcast docs do a good job of showing how this can be achieved programatically, and how hazelcast.jar/hazelcast-default.xml holds the (considerable) default configuration.

What is unclear is: is any XML configuration I supply overlaid upon the settings within hazelcast-default.xml - or simply used in its stead?

Answer 1

I have both my answers, and should like to share them

1. Just like the programatic API, the XML configuration overlays the defaults found in hazelcast.jar/hazelcast-default.xml, consequently ...

2. I can establish a very simple two-member cluster with this hazelcast.xml in the classpath

   <hazelcast>
     <network>
       <join>
         <multicast enabled="false"></multicast>
         <tcp-ip enabled="true">
           <member>192.168.100.001</member> <!-- server A -->
           <member>192.168.102.200</member> <!-- server B, on separate subnet -->
         </tcp-ip>
       </join>
     </network>
   
   </hazelcast>
