Hi,

Is there some change happended in elastic java api in 2.\* version ?  
I was trying the below code in 1.7 and was working fine

> Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name","navneet").build();  
> TransportClient client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9300));

But in elastic 2.1 it is throwing an error saying that :-

> org.elasticsearch.transport.NodeDisconnectedException: [inet[localhost/127.0.0.1:9300]]

I think issue with the latest jars, any suggestion ?

Thanks

A lot of changes yes. Not only in the java client.

But this should work I think unless you changed some `elasticsearch.yml` settings.

Actually, everything works fine for me locally.

I have not changed much in elastic.yml apart from node\_name : Master-Node and Master : true  
and I have only one master node running as of now..
