------------------------------------
Thank you for your comment!

I agreed with you. I will upload it shortly.

Yes, only owner or admin can do operations like start/stop/destroy as you said.
It is not about granular permission.
stopped service can be restarted with existing configuration whenever we want.
unlike stop, destroy is irreversible. once destroy is requested, it will delete
permanently.
when a running service is destroyed by mistake, it is not possible to recover.
that’s the dangerous thing I’m thinking.
so, destroy should be allowed for stopped service only.
> destroying yarn-service is allowed even though running state
