[ https://issues.apache.org/jira/browse/NIFI-12232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17817377#comment-17817377 ] René Zeidler commented on NIFI-12232: - I've encountered the same issue. It's happened since at least 1.23.2, and I can realiably reproduce it on 1.25.0 and 2.0.0-M2 as well. I've been able to create minimal reproduction steps that do not require and non-standard setup. The issue is independent of any specific processors or any complicated flow setup. It _always_ occurs when a node disconnects from the cluster which contains a process group that hasn't been "fully synced". I'll explain what that means in the reproduction steps. h2. Minimal Reproduction Steps # Setup a NiFi {*}cluster with at least 3 nodes{*}, using all default settings. You may adjust {{nifi.cluster.flow.election.max.wait.time}} and {{nifi.cluster.flow.election.max.candidates}} to make the node connection process faster, but this isn't necessary to reproduce the bug. # I'll call the nodes {*}Node A{*}, {*}Node B{*}, and {*}Node C{*}. Open the web interface for Node A and Node B. # On {*}Node A{*}, create a new {*}process group{*}. In that process group, create a very simple flow: GenerateFlowFile going into UpdateAttribute going into a funnel. Start the UpdateAttribute processor. Like this: !image-2024-02-14-13-33-44-354.png! The exact flow doesn't matter, all that's necessary to produce the bug is a *running processor* with an {*}ingoing and outgoing connection{*}. # On {*}Node B{*}, observe that the process group has _automatically synced_ (Right click -> Refresh if you don't want to wait). # On {*}Node A{*}, go to *Menu -> Cluster* (top right hamburger menu). {*}Disconnect Node B{*}. Click refresh (bottom left) until the node has disconnected. # Right after it was disconnected, *connect Node B* again. Click refresh to see the status change. It will change to CONNECTING and quickly back to DISCONNECTED. Check the log file for Node B. You will see the following exception: {{o.a.nifi.controller.StandardFlowService Handling reconnection request failed due to: org.apache.nifi.controller.serialization.FlowSynchronizationException: Failed to connect node to cluster because local flow controller partially updated. Administrator should disconnect node and review flow for corruption.}} [...] {{Caused by: org.apache.nifi.controller.serialization.FlowSynchronizationException: java.lang.IllegalStateException: Cannot change destination of Connection because the current destination is running}} # On {*}Node B{*}, you will get the warning that the node is disconnected from the cluster ({_}This node is currently not connected to the cluster. Any modifications to the data flow made here will not replicate across the cluster.{_}) Go into the process group. Observe that the UpdateAttribute processor is {*}running{*}, which is the direct cause of the exception. h3. Temporary fix # On {*}Node B{*}, *stop* the UpdateAttribute processor. # On {*}Node A{*}, *connect Node B* again. This time it will work and Node B successfully reconnects to the cluster. # However, this only allows Node B to reconnect once. The process group on Node B is still in an inconsistent state and will fail to reconnect the next time. Repeat steps 5 - 7 above to confirm that the issue persists. h3. Permanent fix # On {*}Node B{*}, stop the UpdateAttribute processor and then {*}delete the whole processor group{*}. Since Node B is currently disconnected from the cluster, this will only delete the process group locally on this node. # On {*}Node A{*}, *connect Node B* again. The reconnection will be successfull and the deleted process group will sync back to Node B. Since the whole process group was missing, this will now be a "full sync". # This specific process group on this specific node (Node B) is now "fixed". It will not cause this issue anymore. To confirm, repeat steps 5 and 6 above. You can disconnect and reconnect Node B without issues. h2. Further notes * Instead of deleting the process group, you can also stop the disconnected node completely, delete the flow.json/flow.xml, and start it again. It will join the cluster again, and all process groups will be "fully synced". This fix was described in previous comments, but is not necessary to reproduce the issue. * The fix applies per process group and per node. After fixing the issue for Node B with the "permanent fix" above, it will still affect Node C. If you disconnect and try to reconnect Node C it will throw the same exception. * Also, the group where you initially created the flow (in this example Node A) is _not_ exempt. If you go to Node C, disconnect and try to reconnect Node A, it will throw the same exception. h2.
