I am slightly a newbie to elastic. I need to create a new coordinating only node to use transport client with x-pack security. I am reading here ([https://www.elastic.co/guide/en/x-pack/current/java-clients.html](https://www.elastic.co/guide/en/x-pack/current/java-clients.html)) "Using the Java Node Client with secured clusters is not recommended or supported." can anyone provide details on what that means?

It just means that you should use a Transport Client or the REST client.  
The old fashion Node Client is not supported anymore.

I am using `node v4.5.0` & `npm 1.4.21`. When I am using ES 2.4.0 my node is connecting fine to ES. After upgrading it to 5 its showing ES is down. In my package.json I am seeing `"elasticsearch": "^11.0.1",` this version. In the documentation (5.0 API) I am seeing every thing same as 2.4.0 API. Can you explain how Transport Client or the REST client is used in node to connect to ES 5??? I am not using X-pack in my node.

You are using JavaScript. It's not related to Tranport or REST Java client.  
Open a new thread and explain what your problem is. I actually don't understand what you wrote. May be it's because I'm not a JS dev?
