>                 Key: NIFI-14999
>                 URL: https://issues.apache.org/jira/browse/NIFI-14999
>             Project: Apache NiFi
>          Issue Type: Bug
>          Components: Core Framework
>    Affects Versions: 2.5.0, 2.6.0
>            Reporter: Gabriel Orstadius-Bui
>            Assignee: Matt Gilman
>            Priority: Major
>          Time Spent: 0.5h
>  Remaining Estimate: 0h

> Found this bug in version 2.5, and have confirmed that this bug is not 
> reproducible in 2.4
>  # Create any Record Reader Service (don't enable yet)
>  # Create a PutRecord processor and set the created Record Reader (don't set 
> Record Destination Service)
>  # Go to the Record Reader and enable it, selecting scope "Service and 
> referencing components"
>  # PutRecord will still be invalid (since "Record Distination Service" and 
> Upstream Connection are required), but it is now not possible to change 
> configurations or delete it, Error: "Cannot modify configuration of 
> PutRecord[id=70b8bce2-0199-1000-4805-b0329e43f239] while the Processor is 
> running".
>  # UI also does not offer option to stop processor, only to disable (which 
> does nothing)
> In other words, it seems as if enabling a service with referencing 
> processors, wrongly leads the invalid processor to get stuck in a running 
> state which can't be fixed, rendering the processor (and service) unusable.
> The only solution to this bug I have identified is to stop the entire Process 
> Group, which then will stop the Processor gone rogue.
