---------------------------------
Summary: Upgrading versioned process group overwrites external
service reference
Key: NIFI-5910
URL: https://issues.apache.org/jira/browse/NIFI-5910
Project: Apache NiFi
Issue Type: Bug
Reporter: Bryan Bende
Using two NiFi instances and one NiFi registry...
1) In NiFi 1:
* Create a controller service at the root level
* Create a process group with a processor that uses the service from the root
level
* Start version control
2) In NiFi 2:
* Import the flow and see the processor has an invalid service reference
* Create a service at root level and change processor to use that service
* Notice no local changes to commit, this is correct
3) In NiFi 1:
* Make a change to the processor, just move its position
* Save version 2 of the flow to registry
4) In NiFi 2:
* Upgrade the process group to version 2
* Notice the service reference of the processor is reset back to the invalid
reference
If you did the same steps, but in step 3 you modify something else besides that
processor, then when upgrading in NiFi 2 it retains the correct service
reference. So it is only when the upgrade has changes to the processor with the
external service reference.
