------------------------------------
Hi [~aonishuk], parallel execution is disabled by default, so this patch
shouldn't have changed anything, it must be something else.
When was the last time you measured?

> Issue Type: Task
> Affects Versions: 2.0.0

> Ambari serializes all operations on the node, and by actually parallelizing
> the independent setup activities, deployment time would significantly
> decrease. Ambari stack definition already defines a notion of service
> dependencies, so some basic infra requirements for parallel execution are
> already in place.
> This is a tracking Jira where we can discuss this proposal and work on the
> design/prototype and patch.
