> Key: NIFI-9853
> URL: https://issues.apache.org/jira/browse/NIFI-9853
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.16.0
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Critical
> Fix For: 1.16.1
>
> Time Spent: 20m
> Remaining Estimate: 0h

> Prior to 1.16, when a users chose to Save Flow Definition, the exported .json did not contain a state for Controller Services/processors. When a flow was imported, the state defaulted to DISABLED for services, ENABLED/STOPPED for processors.
> In 1.16, though, the exported JSON does contain the scheduled state. When a flow is imported, any Controller Service whose state is marked as ENABLED immediately becomes enabled, but on import it should remain DISABLED.
> Additionally, on startup, if a node inherits the cluster flow, and the cluster flow indicates that a processor should be stopped while the local flow says it should be running, the node allows the processor to continue running, getting out of state with the cluster.
