Enabling Application Master Web UI Security

By default, the Application Master web UI is not secure and open to everyone. You can configure user authentication or implement a simple, predefined user name and password to secure the UI. Modify the drill-on-yarn.conf configuration file to enable Drill-on-YARN security.

‚ÄčThe following sections describe how to enable security for the Application Master web UI.

User Authentication

You must enable user authentication in Drill if you want Drill-on-YARN to use this feature for security purposes. When user authentication is enabled, the user name and password must match that of the user that started the Drill-on-YARN application.

To secure the Application Master web UI by way of user authentication, modify drill-on-yarn.conf to include the following section with the auth-type set to drill:
drill.yarn.http: {
   auth-type: "drill" 
}

Simple Security

Define a username and password in drill-on-yarn.conf and then restart the Drill-on-YARN Application Master to implement simple security for the Application Master web UI.

Modify the drill-on-yarn.conf configuration file to include the following section, replacing the user-name and password settings with yours, and then restar the Drill-on-YARN Application Master:
drill.yarn.http: {
   auth-type: "simple"
   user-name: "bob"
   password: "secret"
}

When you visit the web UI, a login page prompts you for the username and password that you configured. These are the only valid credentials.
