ambari-server/src/main/resources/stacks/HDP/2.2/configuration/cluster-env.xml 
(line 24)
<https://reviews.apache.org/r/44933/#comment186772>

    Actually, this file must exist for the entire stack and not inside the #.# 
folder.
    The reason being that an EU from HDP 2.1 to 2.3 does the following:
    
    1. Current stack is 2.1
    2. Stop all services
    3. Change stack to 2.3 and save new configs
    4. Start all services on 2.3
    
    Any action before step 3 may need to reference the stack_features 
min_version and max_version of the newer stack it is going to. But that will of 
course be inaccessible at that time.
    
    So we need a single file for the entire stack name.
