> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Oleg Zhurakousky
> Priority: Critical
> Fix For: 1.0.0, 0.7.0
>
>
> in the StandardControllerServiceProvider, we enable a Collection of
> Controller Services but do so in the background with a limited number of
> threads. We need to ensure that all Controller Services have at least become
> ENABLING before returning from this method. Otherwise, Processors that depend
> on them could attempt to start. If this happens, the Processor will be
> invalid because it references a Disabled Controller Service. As a result, the
> Processor will not start. In a clustered environment, we will end up with
> inconsistent run states across the nodes.
