How to get Node status HighLevelRESTClient ElasticSearch

I am using the Java HighLevelRestClient to connect to my ElasticSearch.I was working on a task to get the health status of each nodes.

Tried with :

private string getHighLevelClientInfo(){
try{
ClusterHealthResponse res=restHighLevelClient.cluster().health(new ClusterHealthRequest(),RequestOptions.DEFAULT);
return res.getStatus.name();
}
catch(Exception e){
return "Error";
}
}

While doing so, i was getting all Cluster related information with Status as "Green" and number of nodes=3.

Any help, how to get the node specific information with node status.

Thanks
