------------------------------------
Summary: Update class names when import older flow from registry
Key: NIFI-13613
URL: https://issues.apache.org/jira/browse/NIFI-13613
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 2.0.0-M3
Environment: Ubuntu 22.04
Open JDK 21
NiFi Registry 2.0.0.M3
Reporter: Night Gryphon
I'm trying to migrate from NiFi 1.23 to 2.0.0 using NiFi Registry.
When i import flow to 2.0.0 i get some missing components due to package names
changes for some components like JOLT.
The issue/bug is having such flow prevent cluster nodes to restart/rejoin. Once
node is shutdown or disconnected from cluster it can't come back as it can't
sync flow with master node due to missing components and so node just shutdown.
Furthermore at the master node i can not delete or fix the corrupt process
group as some nodes are unavailable and can't rejoin cluster.
So to recover i has to delete nodes from cluster, delete process group and than
rebuild cluster.
To fix this issue class names has to be checked at the flow import and replaced
according to updates in 2.0.0.
