Looks like JHLRC doesn't have a API to get _cat/nodes API, but it can be easily obtained using the low-level client which is available within JHLRC as shown in below code

private void getNodesAPI(RestHighLevelClient restHighLevelClient) throws IOException {
        RestClient lowLevelClient = restHighLevelClient.getLowLevelClient();
        Request request = new Request(
                "GET",
                "/_cat/nodes?v");
        Response response = lowLevelClient.performRequest(request);
        if (response.getStatusLine().getStatusCode() == 200) {
            System.out.println("resp: \n"+ EntityUtils.toString(response.getEntity()));
        }
    }

Ran above code locally and it works and below is the O/P on console

ip        heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
127.0.0.1           48          99  21    2.59    1.93     1.92 *    opster
