Stack Trace:

```

I am using elasticsearch version 5.5.2

here is the jar I am importing

```
<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>5.5.2</version><!--$NO-MVN-MAN-VER$ -->
</dependency>

```

This runs perfectly fine locally but breaks when I attempt to deploy the war on our server. Any ideas? I am running java 8 and tomcat 8 locally and on my server.

It will help if you can provide the complete stacktrace of the exception and some code snippet of your client initialization.
