AwsConfig able to connect to hazelcast cluster inside EC2 but ClientConfig not able to connect

[rajeshnair]

I am trying to connect a hazelcast client running from outside EC2 to connect to hazelcast instance running inside EC2

I have been able to run the hazelcast instance running using EC2 clustering with access, key secret key etc.

The following code using AWSClient correctly retrieves the server's information as well.
The access key and secret key is same as provided in server

 AwsConfig config = new AwsConfig(); 
        config.setAccessKey("******") ;
        config.setSecretKey("******" );
        config.setRegion("us-east-1" );
        config.setSecurityGroupName("launch-wizard-1");
        config.setEnabled(true);
        AWSClient client = new AWSClient( config );

        Collection<String> ipAddresses = client.getPrivateIpAddresses();
        System.out.println( "addresses found:" + ipAddresses ); 
        for ( String ip: ipAddresses ) {
          System.out.println( ip ); 
        }

        Map<String,String> addresses = client.getAddresses();
        Iterator<Map.Entry<String, String>> iter = addresses.entrySet().iterator();
        while (iter.hasNext()) {
            Map.Entry<java.lang.String, java.lang.String> entry = (Map.Entry<java.lang.String, java.lang.String>) iter
                    .next();
            System.out.println(entry.getKey()+" "+entry.getValue());
        }

The above code when run from my mac using the same prints

addresses found:[172.31.39.10]
172.31.39.10
172.31.39.10 54.172.62.197

But the below code fails to connect to server

ClientAwsConfig clientAwsConfig = new ClientAwsConfig();
        clientAwsConfig.setInsideAws(false );
        clientAwsConfig.setAccessKey("*********" );
        clientAwsConfig.setSecretKey("*************" );
        clientAwsConfig.setRegion("us-east-1" );
        clientAwsConfig.setHostHeader("ec2.amazonaws.com" );
        clientAwsConfig.setSecurityGroupName("launch-wizard-1" );
        clientAwsConfig.setEnabled(true);

        ClientConfig clientConfig = new ClientConfig();
        clientConfig.getNetworkConfig().setAwsConfig( clientAwsConfig );

        HazelcastInstance client = HazelcastClient.newHazelcastClient( clientConfig );
        Collection<DistributedObject> doColl =  client.getDistributedObjects();
        System.out.println(doColl.size());

The above code gives the following error

What could I be missing ?

Silly mistake!

I forgot to provide GroupConfig!
