> Key: NIFI-13009
> URL: https://issues.apache.org/jira/browse/NIFI-13009
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Documentation & Website
> Affects Versions: 2.0.0-M2
> Reporter: Nissim Shiman
> Assignee: Nissim Shiman
> Priority: Major
> Fix For: 2.7.0
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Disconnected nifi nodes can be modified with new flows even though they are
> disconnected.
> When the node rejoins the cluster, however, these flows can be quietly
> removed.
> For example, on a 3 node cluster graph with a blank graph, disconnect one of
> the nodes.
> On the disconnected node, set up and start:
> GenerateFlowFile -> UpdateAttribute (where UpdateAttribute has success
> relationship terminated)
> On gui of one of the remaining connected nodes, reconnect disconnected node.
> It will reconnect successfully and all node graphs will be blank.
> Cluster docs and/or logs should capture this situation better.
