Question

使用单个查询从索引中获取100K和文档。为此，使用的是ScrollSearch API。之后，逐个迭代每个文档，并向其中添加一个字段，并为此创建一个新索引。

我使用RestHighLevelClient来实现Java代码和ElasticSearch之间的连接。我为Timeout小时设置了25个选项（setMaxRetryTimeoutMillis（90000000））。

但是，30分钟后仍会出现以下异常

Exception in thread "main" java.io.IOException: An existing connection was forcibly closed by the remote host

我的ElasticSearch服务器正在远程计算机上运行。一旦遇到此异常，我的远程计算机ES服务器也会自动关闭。

请在下面找到我为RestHighLevelClient创建实例的代码。

private static RestClientBuilder builder = RestClient.builder(new HttpHost("My_Server.com", 9200, "http"), 
            new HttpHost("My_Server.com", 9201, "http"))
            .setRequestConfigCallback(new RestClientBuilder.RequestConfigCallback() {
                @Override
                public RequestConfig.Builder customizeRequestConfig(RequestConfig.Builder requestConfigBuilder) {
                    return requestConfigBuilder.setConnectTimeout(90000000)//25hours
                            .setSocketTimeout(90000000);

                }
            })
            .setMaxRetryTimeoutMillis(90000000);


    private static RestHighLevelClient instance4 = new RestHighLevelClient(builder);

    public static RestHighLevelClient getInstance3() {
        return instance4;
    }
