Hi,

I am trying to use the ES node based client instead of transport and I keep  
getting this error (also, I'm coding in JAVA):

Exception in thread "Timer-0" java.lang.ExceptionInInitializerError

at com.priceline.argus.es.gds.PushGdsToES.main(PushGdsToES.java:38)

... 4 more

Here is a snippet of my code:

static Settings settings = ImmutableSettings.settingsBuilder().put(  
"network.host","hostName").put("cluster.name", "clusterName").build();

private static Node node = nodeBuilder().settings(settings).client(true  
).data(false).node();

private static Client esClient = null;

public static Client getClient() {

if (esClient == null) { esClient = node.client(); }

return esClient;

}

I am thinking that the only thing I'm missing is the port number when I  
create the settings but I could be wrong. When I use the transport  
protocol, everything works fine but I am also specifying the port number  
when I use that protocol.

Thanks,

Phil
