I am unable to start a transport client. My code is -

```
Settings settings = Settings.builder()
	       .put("client.transport.sniff", true).build();

TransportClient client = new PreBuiltTransportClient(settings)
	     .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

```

The error I get is as below. Note I am not running any unit tests, though there may be some unit tests in the classpath. I have checked that none of them have  
@RunWith (Parameterized.class)

I think it is dues to some maven dependancies, but I don't know which one - and I have a gigantic pom.xml and lots of associated files. So I don't know what to update!

That's the problem, you have randomized runner on your class path. You need to use the Maven dependency tree to find out where it is coming from.

I think we need to use the Randomized runner to create a PreBuiltTransportClient?

I have tried using the annotation on my test class as  
@RunWith(com.carrotsearch.randomizedtesting.RandomizedRunner.class)

but this produces threading issues.  
(Even if I use annotation)  
@ThreadLeakScope(ThreadLeakScope.Scope.NONE)
