Re: Can "Delete" button on Ambari UI be disabled ?

Hi Di,

From an end user perspective, you can also use the RBAC features in admin view 
to assign “Cluster Operator” or lower role to the users you don’t want 
add/delete service available.

Hi Di,

Existence of "Delete" button for a service is not stack driven.
Although on clicking delete action, UI asks end-user to first stop and 
delete any service that depends on "being deleted" service.
This logic is stack driven.

So when user tries to delete a zookeeper service, ambari-web will ask user 
to first delete other "many" services like HDFS, YARN, etc first since they are 
marked to require zookeeper service in their service definition.

Again these restrictions are stack driven but these are made by ambari-web 
client and so user can always use API to delete a service directly. In this 
case all "Delete Service" API checks is that no host component of service 
should be in running state.

Hello folks,

Can "Delete" button on Ambari UI be disabled (via some stack service
configuration ) ?  For example, disable the Delete button for Zookeeper as
many services depend on it ?

Thanks.
