带有亚马逊ElasticSearch的Java RestHighLevelClient

Question

我想知道这里是否有人使用过RestHighLevelClient连接到亚马逊网络服务ElasticSearch。不确定这是否是亚马逊网络服务ElasticSearch支持的东西。我现在每次尝试连接时都会收到一个ConnectionClosedException。

这就是我所拥有的：

public SearchResponse getQuery(){
    RestHighLevelClient client = new RestHighLevelClient(
            RestClient.builder(new HttpHost("localhost", 4430, "http")));
    SearchRequest searchRequest = new SearchRequest("msglog-dev-2018.05.21");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    searchSourceBuilder.query(QueryBuilders.matchAllQuery());
    searchRequest.source(searchSourceBuilder);
    SearchResponse searchResponse = null;
    try{
        searchResponse =client.search(searchRequest);
    }catch(IOException e){
        e.printStackTrace();
    }
    return searchResponse;
}

我得到的错误是
