> Relates to NIFI-5227
> Steps to reproduce:
> # Create a simple flow: *GenerateFlowFile + UpdateAttribute*. Ensure both processors have valid state.
> # Commit flow to a registry.
> # Remove connection between processors or do something else to move *UpdateAttribute* in invalid state.
> # Commit flow to a registry.
> # Change flow version to "1". *UpdateAttribute* should be valid now.
> # Run *UpdateAttribute*
> # Change flow version to "2". Ensure *UpdateAttribute* has invalid state now.
> # Change flow version back to "1".
> You will see error message _"Failed to update Flow on all nodes in cluster due to Cannot modify Processor configuration while the Processor is running"._
> _!image-2020-11-24-15-57-26-995.png!_
> Error message for single node (non cluster) will be similar.
> See attached patch. My solution is quite simple but I don't sure may be it is not good enough.
