Hi I am using transport client to connect to the elastic search cluster and getting this exception

I am using elastic search 5.5.0 and this is the way i connect to ES

public static TransportClient getTransportClient(){  
TransportClient client = null;  
try{  
Settings settings = Settings.builder()  
.put("client.transport.sniff",true)  
.put("[cluster.name](http://cluster.name)", System.getenv(SharedConstant.CLUSTER))  
.build();  
client = new PreBuiltTransportClient(settings)  
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(System.getenv(SharedConstant.HOST1)), 9300))  
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(System.getenv(SharedConstant.HOST2)), 9300));  
}catch (Exception e){  
[LOG.info](http://LOG.info)(e.getMessage());  
throw new RuntimeException(e);

```
        }
        return client;
    }

```

Any help in resolving this would be appreciated.  
Rohit

I think that you’re using Netty elsewhere in your application, yes? If so, you have two choices:

- force the transport client to initialize before any other component that uses Netty initializes
- set the system property `es.set.netty.runtime.available.processors` to `false`

You should prefer the first option, the second option is an escape hatch.
