Question

我在远程计算机上运行我的ElasticSearch Server。我正在尝试从本地计算机上为我的pdf文档编制索引。

我正在使用RestHighLevelClient创建RestClientBuilder实例，并且还将超时设置为setMaxRetryTimeoutMillis(60000)。

经过处理后，少数文档出现An existing connection was forcibly closed by the remote host异常。

请在为RestHighLevelClient作为单例创建实例的地方找到我的代码。

private static RestClientBuilder builder = RestClient.builder(new HttpHost("Server_machine.com", 9200, "http"), 
new HttpHost("Server_machine.com", 9201, "http"))
.setRequestConfigCallback(new RestClientBuilder.RequestConfigCallback() {
    @Override
    public RequestConfig.Builder customizeRequestConfig(RequestConfig.Builder requestConfigBuilder) {
        return requestConfigBuilder.setConnectTimeout(5000)
                .setSocketTimeout(600000);

    }
})
.setMaxRetryTimeoutMillis(60000);


private static RestHighLevelClient instance4 = new RestHighLevelClient(builder);

public static RestHighLevelClient getInstance3() {
    return instance4;
}

请找到错误的完整堆栈跟踪。

我们可以将setConnectTimeout(5000)设置为几个小时，因为我的代码将运行很长时间。
