> During an express upgrade, when performing an upgrade between stack versions, the wrong
repository/stacks/hooks are sent down during the {{post-upgrade}} step:
> {code}
>       <component name="FOO">
>         <pre-upgrade>
>           <task xsi:type="execute" hosts="all">
>             <script>scripts/upgrade.py</script>
>             <function>bar</function>
>           </task>
>         </pre-upgrade>
>         <upgrade>
>           <task xsi:type="restart-task"/>
>         </upgrade>
>         <post-upgrade>
>           <task xsi:type="execute" hosts="any">
>             <script>scripts/upgrade.py</script>
>             <function>baz</function>
>           </task>
>         </post-upgrade>
> {code}
> In both the {{pre-upgrade}} and {{post-upgrade}} commands, the scripts folder location
refers to the old stack. The restart/start command, however, is correct.
> It appears as though the problem is found here:
> https://github.com/apache/ambari/blob/branch-2.6/ambari-server/src/main/java/org/apache/ambari/server/controller/internal/UpgradeResourceProvider.java#L1052-L1055
> {code:title=makeActionStage()}
>     // the ru_execute_tasks invokes scripts - it needs information about where
>     // the scripts live and for that it should always use the target repository
>     // stack
>     applyRepositoryAssociatedParameters(wrapper, effectiveRepositoryVersion.getStackId(),
params);
> {code}
> It uses the effective stack ID which during an express upgrade is the source stack of
the upgrade.
