Description

After enabling kerberos, if you browse to Service > Configs, you are see properties for Ambari Principals *_principal_name. For example, smokeuser_principal_name can be seen in all services, and hbase_principal_name can be see in HBase.
Attached screen shot shows the properties showing thru the Service > Hbase > Configs tab.
There properties should not be editable by the user in the UI. These values are generated by the kerb infra based on the descriptor pattern, and a user editing these can cause issues.
