             Summary: Kerberos: disable edit on principal_name configs
                 Key: AMBARI-10094
                 URL: https://issues.apache.org/jira/browse/AMBARI-10094
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.0.0
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
            Priority: Critical
             Fix For: 2.0.0


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.
