>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.5.2
>            Reporter: Jonathan Hurley
>            Assignee: Jonathan Hurley
>            Priority: Blocker
>             Fix For: 2.5.2

> Currently, the stack tools:
> - {{cluster-env/stack_features}}
> - {{cluster-env/stack_tools}}
> - {{cluster-env/stack_root}}
> Are bound to the {{cluster-env}} without any sort of scoping. This prevents 2 sets of stack tools from co-existing. Although Ambari doesn't support more than a single stack in 2.x, we do support upgrades from one stack vendor to another. Therefore, we need this support to send the right tools on the commands.
> This will involve the following work:
> - Changing the existing stack tools/features/root to have a stack name as the key in the JSON
> - Altering the existing {{cluster-env}} tools on upgrade
> - Ensuring that the stack tools/features for a repository's stack exist when distributing that stack
> - Changing any Python code which references the stack tools (stack_tools.py, alerts, etc)
