eureka unknownHostException in service discovery
<p>I've two microservices,</p>

<ol>
<li>eureka-client-1 running on localhost:8081</li>
<li>eureka-client-2 running on localhost:8082</li>
</ol>

<p>Both these are DiscoveryClients registered with 'eureka-server' running on localhost:8761.</p>

<p>In code snippet below, I'm trying to call eureka-client-2 from eureka-client-1. Instead of calling <a href="http://localhost:8082" rel="noreferrer">http://localhost:8082</a>, i want to call <a href="http://eureka-client-2" rel="noreferrer">http://eureka-client-2</a> but this throws java.net.UnknownHostException during Eureka service discovery.</p>

<p>After searching, I found that i need to use "Brixton" to get it done.  </p>

<p>Is there a way to do it with Camden.SR3 ?</p>

<p>Please suggest.</p>

<pre><code>@Component
public class HystrixDemoService {   

    @Bean
    @LoadBalanced
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

    @HystrixCommand(fallbackMethod = "getFallbackCustomerName")
    public String getCustomerName() {
        RestTemplate restTemplate = new RestTemplate();
        URI uri = URI.create("http://eureka-client-2");     // fails here
        return restTemplate.getForObject(uri, String.class);
    }

    public String getFallbackCustomerName() {
        System.out.println("coming inside fallback method");
        return "Resillient Customer";
    }
}
