I am trying to use Java 2.3 client API to connect to ElasticSearch has two nodes configration(1 master, 1 data node). However its stuck at the TransportClient.builder().settings(settings).build().  
My code which create a client:  
this.elasticsearchEndpoint = elasticSearchEndpoint;  
this.elasticsearchPort = elasticSearchPort;  
Settings settings = Settings.settingsBuilder()  
.put("[cluster.name](http://cluster.name)", elasticSearchClusterName)  
.put(ELASTICSEARCH\_CLIENT\_TRANSPORT\_SNIFF\_KEY, true).build();  
TransportClient.Builder builder = TransportClient.builder().settings(settings);  
log.debug("ElasticsearchEmitter using raweventkcl endpoint");  
this.elasticsearchClient = builder.build();  
log.debug("ElasticsearchEmitter using raweventkcl endpoint");  
There is log before builder. build();  
but noting else after that.

log:

Any idea about this.
