add BasicConfigurator.configure() to your code before instantiating the Client so that you can provide the error message that's causing issues. — Alcanzar

If there is nothing else to your code, the issue is that the ES thread on it's own won't keep the program alive. You need to have a thread of your own to keep it alive.. for example:

    BasicConfigurator.configure();
    Node node = NodeBuilder.nodeBuilder().local(true).node();
    node.start();
    while (!node.isClosed()) {
        try {
            Thread.sleep(60*1000);
        } catch (InterruptedException e) {
            node.close();
        }
    }
    node.stop();
