---------------------------------------
Summary: When adding more nodes in a Nifi Cluster mode, new nodes
cannot find existing parameter contexts
Key: NIFI-10338
URL: https://issues.apache.org/jira/browse/NIFI-10338
Project: Apache NiFi
Issue Type: Bug
Components: NiFi Stateless
Affects Versions: 1.16.1
Environment: Kubernetes, Docker Image is based on Alpine/Java
amazoncorreto: 8u312
Reporter: Andreas Adamides
My setup is Nifi in Cluster mode, initially with 1 node. I have created a
parameter context and associated it with process groups(>1) in my Canvas. When
I increase to three nodes(they successfully connect in the cluster), and when I
reach the Nifi UI, to view/edit that very same parameter context I get the
error:
{code:java}
No parameter context with id: "<Uuid>"
{code}
I also get the same error when I try to reach the parameter context via the
APIs. When I list all parameter contexts this param context shows up, but when
I try to modify or even delete via API call, I get the same error.
When I scale back to 1 node, repeat the above in the Nifi UI, I can view/edit
the parameter context without any issues.
If it matters I am using [https://github.com/cetic/helm-nifi] to deploy my Nifi
Cluster. I suspect there might be a sync issue at some point, causing the new
nodes to not know about that parameter context, but I cannot tell which one.
Can anyone please suggest a fix or any pointers as to how to approach this
issue?
