I'm creating a TransportClient instance in elasticsearch. Below is the code  
for the same. The issue is I'm trying to lower the number of threads  
spawned with the threadpool that TransportClient initiates.

public static TransportClient getTransportClient(String ip, int port) {

```
ImmutableSettings.Builder settings = ImmutableSettings
        .settingsBuilder();
settings.put("cluster.name", "elasticsearch");
settings.put("threadpool.bulk.type", "fixed");
settings.put("threadpool.bulk.size" ,5);
settings.put("threadpool.bulk.queue_size", 5);
settings.put("threadpool.index.type" , "fixed");
settings.put("threadpool.index.size" , 5);
settings.put("threadpool.index.queue_size" , 10);
settings.put("threadpool.search.type", "fixed");
settings.put("threadpool.search.size" ,5);
settings.put("threadpool.search.queue_size", 5);
settings.build();

TransportClient instance = new TransportClient(settings)
        .addTransportAddress(new InetSocketTransportAddress(ip, port));

return instance;

```

}

But what ever settings I use my elasticsearch always initialing the  
threadpool with 12 threads. Guess that is the 4 time of CPU while  
calculating the threadpool size.

Please let me know what is the configuration to get the desirable threads.

Thanks,  
Bagui
