Node.js集群失败而不是重定向到其他工作者

Question

我遇到一个问题，我有两个工作人员正在运行Node.js群集，而我正在使用for循环向工作人员发送大量请求。这些请求仅针对一个工作人员，因为负载不足以使操作系统需要使用第二个工作人员。但是，当我杀死目标worker（kill worker.pid）时，不是让第二个worker继续接收请求，所有请求都会停止，并且带有for循环的程序会挂起并最终失败/获得异常。

我不想在客户端更改代码，也无法弄清楚如何在服务器端处理此问题。

这是我的服务器端代码：

var cluster = require('cluster');

if(cluster.isMaster){
    for(var j=0; j<2; j++)
        cluster.fork();

    cluster.on('online', function(worker){
        console.log('worker ' + worker.process.pid + ' alive');
    });

    cluster.on('exit', function(worker, code, signal){
        console.log('worker ' + worker.process.pid + ' died');
        cluster.fork();
    });
}
else {
    /*Includes and global variables*/
    var http = require('http');
    http.createServer(function (req, res){
        var headers = {};
        headers["Access-Control-Allow-Origin"] = "*";
        headers["Access-Control-Allow-Methods"] = "POST, GET, PUT, DELETE, OPTIONS";
        headers["Access-Control-Allow-Credentials"] = true;
        headers["Access-Control-Allow-Headers"] = "X-Requested-With, Access-Control-Allow-Origin, X-HTTP-Method-Override, Content-Type, Authorization, Accept";
        res.writeHead(200, headers);

        console.log("test");
        res.end("Response sent");
    }).listen(8070);
}

这是我的客户代码：

for(int i=0;i<2000;i++)
        {
            payLoad = "{\"otoo\":{\"keyName"+i+"\":\"valueName"+i+"\"}}";
            System.out.println(payLoad);
            StringEntity reqEntity = new StringEntity(payLoad);
            reqEntity.setContentType("application/json");
            httpPostRequest.setEntity(reqEntity);

            HttpResponse httpResponse = httpClient.execute(httpPostRequest);

            System.out.println("----------------------------------------");
            System.out.println(httpResponse.getStatusLine());
            System.out.println("----------------------------------------");

            HttpEntity entity = httpResponse.getEntity();

            byte[] buffer = new byte[1024];
            if (entity != null) {
                InputStream inputStream = entity.getContent();
                try {
                    int bytesRead = 0;
                    BufferedInputStream bis = new BufferedInputStream(
                            inputStream);
                    while ((bytesRead = bis.read(buffer)) != -1) {
                        chunk = new String(buffer, 0, bytesRead);
                        System.out.println(chunk);
                    }

                } catch (IOException ioException) {

                    ioException.printStackTrace();
                } catch (RuntimeException runtimeException) {

                    httpPostRequest.abort();
                    runtimeException.printStackTrace();
                } finally {

                    try {
                        inputStream.close();
                    } catch (Exception ignore) {
                    }
                }
            }
        }

以下是例外：
