How can I change the default stack version and build id?

[Discovery]

Hi Ambari experts,


                     I have a requirement for defining my own stack with 
following the Ambari rule, from my understanding, HDP is just one of the 
defined stacks, when I try to define a new HDP-similar stack and package all 
RPMs, how I can make Ambari knows and find my own HDP-similar installation 
packages. For example, myownstack-1.0.0.0-1234 .


                    Where does the Ambari python code read the stack 
version/build id? And where does the version-reading Python code locate in 
Ambari source code? Now I find Ambari always read HDP stack and version RPM 
when doing installation.:-(


                    I do not know if I need to define my own files as below in 
the HDP-similar package?
                    


                 Hopefully I have described the problem clearly, ;-) Thanks you 
in advance!
