Using the Ranger Key Management Service
Ranger KMS can be accessed at the Ranger admin URL, http://$hostname:6080. Note, however, that the login user for Ranger KMS is different than that for Ranger. Logging on as the Ranger KMS admin user leads to a different set of screens.
Role Separation
By default, Ranger admin uses a different admin user (keyadmin) to
manage access policies and keys for Ranger KMS.
The person accessing Ranger KMS via the keyadmin user should be a
different person than the administrator who works with regular Ranger access policies.
This approach separates encryption work (encryption keys and policies) from Hadoop
cluster management and access policy management.
