What version of Elasticsearch are you trying to connect to, and what version are you using for the client libraries? ---

Then you have something wrong with your client configuration/classpath. `org.elasticsearch.shield.ShieldPlugin` is a plugin for Elasticsearch 1 and 2. You shouldn't be using it as part of a 5.5 client. ---

The error message that you included in your original post lists that class. It must have come from somewhere, and it's not part of the 5.x transport client. You need to work out where it's coming from, because it looks like the source of your problems. ---
