"Node Discovery Disabled" in Elastic Search - elasticsearch

Question

I used below Java code on UBUNTU and I am getting "Node Discovery Disabled". Because of this I am not able move forward.
Could anyone please help me out solving this problem.
public static JestClient JestConfiguration(){
// Configuration
ClientConfig client = new ClientConfig.Builder("http://localhost:9200")
.multiThreaded(true).build();
System.out.println("\nclient configured via:- "+client);
// Construct a new Jest client according to configuration via factory
JestClientFactory factory = new JestClientFactory();
factory.setClientConfig(client);
System.out.println("\nJestClientFactory Via:-"+factory);
JestClient jestClient = factory.getObject();
System.out.println("\njestClient via:-"+jestClient);
//jestClient.shutdownClient();
return jestClient;
}

I am not sure what version you are using. I am using 0.1.2 and the factory I have only has a setHttpClientConfig method. So I used the HttpClientConfig instead, which extends ClientConfig. That point aside, the builder has two methods you'll want:
discoveryEnabled
discoveryFrequency
These set node node discovery and how frequently to poll.
HttpClientConfig httpClientConfig = new HttpClientConfig.Builder("http://localhost:9200")
.discoveryEnabled(true)
.discoveryFrequency(10l, TimeUnit.SECONDS)
.multiThreaded(true)
.build();
JestClientFactory factory = new JestClientFactory();
factory.setHttpClientConfig(httpClientConfig);
