RestHighLevelClient 在尝试向 ElasticSearch 发送请求时给出“无法识别的参数”

Question

我正在尝试连接到我的应用程序中的一个本地 ES 系统。以前它是一个不同的集群。最近，我们的 ES 团队将其迁移到启用了基本身份验证的不同集群。我编写了以下代码来初始化 HLRC。

final BasicCredentialsProvider basicCredentialsProvider = new BasicCredentialsProvider();
                basicCredentialsProvider
                    .setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("Username", "Password"));
                RestClientBuilder builder = RestClient.builder(
                        new HttpHost(elasticSearchType.getHost(), 9200, "https"))
                    .setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                        @Override
                        public HttpAsyncClientBuilder customizeHttpClient(
                            HttpAsyncClientBuilder httpClientBuilder) {
                            return httpClientBuilder
                                .setDefaultCredentialsProvider(basicCredentialsProvider);
                        }
                    });
                return new RestHighLevelClient(builder);

我收到以下错误

 reason=request [/index/_search] contains unrecognized parameters: [batched_reduce_size], [ccs_minimize_roundtrips], [ignore_throttled], [max_concurrent_shard_requests], [typed_keys]]

您能否建议我需要做什么才能连接到本地 ES？

请使用与es版本相同的依赖。在浏览器中输入http://127.0.0.1:9200/即可查看es版本
