Hadoop的版本是3.0.3。

Linux 信息如下：

LSB Version:    :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
Distributor ID: RedHatEnterpriseServer
Description:    Red Hat Enterprise Linux Server release 7.5 (Maipo)
Release:        7.5
Codename:       Maipo .

我已经测试了调用api测试/集群路径，结果可以正常返回。

这意味着服务器试图将剩余的字节刷新到客户端，但客户端在发送所有这些字节之前关闭了连接。

当用户离开页面或在发送响应的全部内容之前关闭选项卡时，Web 浏览器经常会发生这种情况。

这种情况更常发生在互联网连接不稳定的客户端，例如移动客户端（例如，当他们切换塔，或从移动到 wifi，或从 wifi 到移动等时）

当客户端根本没有读取整个响应并关闭连接时，这种情况也经常发生。这通常是由于客户端未正确遵循 HTTP 规范造成的。

示例：如果客户端知道它会在完成后关闭连接，它应该在请求中添加Connection: close 标头。

客户端读取响应直到它得到它想要的，然后关闭连接。 （例如在读取 JSON 或 XML 时，它将一直读取到 JSON 或 XML 完成，但不会读取其后的任何其他数据，甚至是空格）。这是一个让许多使用 3rd 方解析库的开发人员感到惊讶的事实。好的库有特定的配置选项可以一直读取直到软 EOF（例如：持久连接上的 HTTP 响应结束）

  • 嗨，joakim。感谢您的回答，基于您的分析。我跟踪了源码，发现确实是这个原因。接下来我会看看为什么链接坏了
