> 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.
