YUBI LEE updated AMBARI-25891:
------------------------------
    Description: 
In short, when regenerating keytabs or changing configuration in Kerberos tab 
in side bar,  ambari-server will changes configurations which are different 
from ones in kerberos.json of stack.
It is caused by missing query parameter, {{config_update_policy=none}}. (refer 
to 
https://github.com/apache/ambari/blob/release-2.7.6/ambari-web/app/utils/ajax/ajax.js#L1985)
And also, I think it should allow administrators to choose whether to generate 
only missing keytabs when they change configuration in Kerberos tab. It should 
use {{regenerateKeytabs}} instead of {{restartServicesAfterRegenerate}}. 
(https://github.com/apache/ambari/blob/release-2.7.6/ambari-web/app/controllers/main/admin/kerberos.js#L575)

I will make a PR about this issue soon!
