Step 19: (Optional) Enable Authentication for HTTP Web-Consoles for Hadoop Roles
Authentication for access to the HDFS, MapReduce, and YARN roles'
web-consoles can be enabled via a configuration option for the appropriate service. To enable
this authentication:
- From the Services tab, select the service (HDFS, MapReduce, or YARN) for which you want to enable authentication.
- From the Configuration tab, select View and Edit.
- Under the Service-Wide > Security category, check the Enable
Authentication for HTTP Web-Consoles property, and Save the your changes.
This will trigger a command to generate the new credentials required for this.
- Once the command finishes, restart all roles of that service.
