> 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: 2.1.0
>
> Attachments: AMBARI-10094.patch, principal_names.tiff
>
>
> 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.
