elasticsearch Connection reset by peer如何处理

如何处理：
代码的心跳代码删除，服务linux内核参数修改 客户端时间要小于服务端时间#异常代码
public RestHighLevelClient elasticsearchClient() {// 初始化 RestClient, hostName 和 port 填写集群的内网 IP 地址与端口
//        String[] hosts = nodes1.split(",");
//        HttpHost[] httpHosts = new HttpHost[hosts.length];
//        for (int i = 0; i < hosts.length; i++) {
//            httpHosts[i] = new HttpHost(hosts[i], port1, "http");
//        }String[] hosts = uris.split(":");HttpHost[] httpHosts = new HttpHost[1];httpHosts[0] = new HttpHost(hosts[0], Integer.valueOf(hosts[1]), "http");// 设置认证信息CredentialsProvider credentialsProvider = new BasicCredentialsProvider();credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(username, password));RestClientBuilder builder = RestClient.builder(httpHosts);//异步链接延时配置builder.setRequestConfigCallback(requestConfigBuilder ->requestConfigBuilder        .setConnectTimeout(5000) //5秒.setSocketTimeout(5000 * 1000).setConnectionRequestTimeout(5000 * 1000));//异步链接数配置builder.setHttpClientConfigCallback(httpClientBuilder -> {//最大连接数100个httpClientBuilder.setMaxConnTotal(100);//最大路由连接数httpClientBuilder.setMaxConnPerRoute(100);httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);// 设置KeepAlive为5分钟的时间，不设置默认为-1，也就是持续连接，然而这会受到外界的影响比如Firewall，会将TCP连接单方面断开，从而会导致Connection reset by peer的报错

httpClientBuilder.setKeepAliveStrategy((response, context) -> TimeUnit.MINUTES.toMillis(3))
.setDefaultIOReactorConfig(IOReactorConfig.custom().setIoThreadCount(1).setSoKeepAlive(true).build());

        return new RestHighLevelClient(builder);}

正确代码：

 public RestHighLevelClient elasticsearchClient() {// 初始化 RestClient, hostName 和 port 填写集群的内网 IP 地址与端口
//        String[] hosts = nodes1.split(",");
//        HttpHost[] httpHosts = new HttpHost[hosts.length];
//        for (int i = 0; i < hosts.length; i++) {
//            httpHosts[i] = new HttpHost(hosts[i], port1, "http");
//        }String[] hosts = uris.split(":");HttpHost[] httpHosts = new HttpHost[1];httpHosts[0] = new HttpHost(hosts[0], Integer.valueOf(hosts[1]), "http");// 设置认证信息CredentialsProvider credentialsProvider = new BasicCredentialsProvider();credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(username, password));RestClientBuilder builder = RestClient.builder(httpHosts);//异步链接延时配置builder.setRequestConfigCallback(requestConfigBuilder ->requestConfigBuilder//.setConnectTimeout(5000) //5秒//.setSocketTimeout(5000 * 1000).setConnectionRequestTimeout(5000 * 1000));//异步链接数配置builder.setHttpClientConfigCallback(httpClientBuilder -> {//最大连接数100个httpClientBuilder.setMaxConnTotal(100);//最大路由连接数httpClientBuilder.setMaxConnPerRoute(100);httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);// 设置KeepAlive为5分钟的时间，不设置默认为-1，也就是持续连接，然而这会受到外界的影响比如Firewall，会将TCP连接单方面断开，从而会导致Connection reset by peer的报错httpClientBuilder.setDefaultIOReactorConfig(IOReactorConfig.custom().setSoKeepAlive(true).build());return httpClientBuilder;});return new RestHighLevelClient(builder);}
