Hi, I have 3 Elastic Search Nodes (1.0.2) setup which are behind a loadbalancer. We have some code written which uses transport client to connect to independent nodes and populate data but the same code when we point to loadbalancer and provide the cluster name it throws an error : org.elasticsearch.client.transport.NoNodeAvailableException: No node available Please let me know is there any different mechanism to connect to Elastic Search through load balancer ?

After Enabling client.transport.sniff parameter it is able to connect , but it is connecting all of the nodes in the cluster. Ideally querying the load balancer should return the response to which node to redirect will be taken care by the load balancer. Is there any problem with the Java code or load balancer settings ?
