How to use the ResourceManager web interface as an user
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)
You should set the access control list by changing the default configuration of:
yarn.resourcemanager.zk-aclfrom
world:anyone:rwcdato something else,which is Cluster-specific
The ACLs the ResourceManager uses for the znode structure to store the internal state.
