如何将ResourceManager Web界面用作用户 [英] How to use the ResourceManager web interface as an user

问题描述

每次我尝试使用Hadoop资源管理器Web界面（

解决方案

用户信息来自HttpServletRequest＃getRemoteUser（）。

1.如果您部署了不安全的集群，将用户名传递给服务器的最简单方法是使用url参数。例如， http：// localhost：8088 / cluster？user.name = babu <
2.如果您部署了安全群集，则可能使用Kerberos身份验证。您可以使用 kinit 来获取kerberos tgt，然后配置浏览器进行协商。 （针对firefox的 network.negotiate-auth.trusted-uris ，以及针对铬的），我相信这里有很多答案）

有关更多信息，可以查看hadoop官方文档（ https://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-common/HttpAuthentication.html ）

Every time i try to use the Hadoop Resource Manager web interface (http://resource-manger.host:8088/cluster/) i show up logged in as dr.who.

My question, how can I login as another user? In this case i want to login as myself and have a higher lever of privileges than dr.who.

解决方案

The user infomation is got from HttpServletRequest#getRemoteUser().
1. If you deployed an insecure cluster, the simplest way to pass the username to server is by url parameter. For example, http://localhost:8088/cluster?user.name=babu
2. If you deployed a secure cluster, you probably use Kerberos authentication. You can use kinit to get a kerberos tgt, then configure the browser to negotiate. (network.negotiate-auth.trusted-uris for firefox, and --auth-server-whitelist for chromium. I'm sure there's lots of answers about this)

For more information, you can check hadoop official documentation.(https://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-common/HttpAuthentication.html)
