In order to take advantage of balancing the load between the nodes of the cluster. I used a DNS pointed to VIP that does a round-robin load balancing among the nodes.

The cluster would not be really useful if I cannot take away nodes and add nodes to the cluster as I wish without any coding change. The drawback in hiding the cluster behind the VIP is that you don't know which node the java code client is going to get in order to process a search request. This is causing an issue in the client code. Since I only have one Transport Addre
