Step 18: (Optional) Enable Authentication for HTTP Web Consoles for Hadoop Roles

Minimum Required Role: Configurator (also provided by Cluster Administrator, Full Administrator)

Authentication for access to the HDFS, MapReduce, and YARN roles' web consoles can be enabled using a configuration option for the appropriate service. To enable this authentication:
  1. From the Clusters tab, select the service (HDFS, MapReduce, or YARN) for which you want to enable authentication.
  2. Click the Configuration tab.
  3. Expand Service-Wide > Security, check the Enable Authentication for HTTP Web-Consoles property, and save your changes.

    A command is triggered to generate the new required credentials.

  4. Once the command finishes, restart all roles of that service.
