> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Reporter: Daniel Ueberfluss
> Assignee: Koji Kawamura
> Priority: Major
>
> Would like to have a user role that allows a user to stop/start processors
> but perform no other changes to the dataflow.
> This would allow users to address simple problems without providing full
> access to modifying a data flow.
