------------------------------------

             Summary: Unable to update NiFi Variables despite stopping all processors
                 Key: NIFI-6844
                 URL: https://issues.apache.org/jira/browse/NIFI-6844
             Project: Apache NiFi
          Issue Type: Bug
          Components: Variable Registry
    Affects Versions: 1.10.0
            Reporter: Advith Nagappa


I am giving NiFi-1.10.0 a spin ((I use nifi-1.7.1 in production) and i used the rest-api to
create my "graph/flows" in nifi with several variables, connections, controllers etc. All
seemed to work well until i tried updating (modifying) one of the variables.

```
{color:#262626}Unable to complete variable update request: Failed to update Variable Registry
because failed while performing step: Applying updates to Variable Registry{color}
```

On inspecting the logs, I see:

I am pretty sure I had stopped ALL the processors and controller services. I even went as
far as disabling everything just to see if there is an something referencing the registry.
But I still received the same issue.
