YARN + 如何调试 wget

YARN + 如何调试 wget

我们正在使用wgetVIA 端口测试从到的8088连接ResourceManager02ResourceManager01

  • 两个资源管理器都是 YARN 服务的一部分,并且每个资源管理器服务都安装在 RHEL 7.9 版本上

如下所示

You have new mail in /var/spool/mail/root

正如我们上面看到的,我们有错误 HTTP request sent, awaiting response... 302 Found

实际上连接需要 2-3 分钟而不是 1 秒

是否有可能调试这种行为,为什么wget没有达到与机器的连接ResourceManager01

我们进行这个测试是因为我们在二级资源管理器ResourceManager02和主资源管理器之间的连接上遇到了问题 - ResourceManager01

两个资源管理器都是 Hadoop 集群的一部分(HDP 2.6.5 版本)

我们从 Ambari UI 收到以下警报

Connection failed to http://ResourceManager01.ggtp:8088 (timed out)
