Hello. We wish to identify the Primary cluster node within our flow. I've scoured the REST APIs and haven't been able to find a way to do this. Has anyone figured out a way to do this? I am running NiFi 1.8. My goal is to develop a flow that distributes subsets of flow processing to all but the Primary node. The Primary node does all the ListFile reads across many workflows, and I want to distribute the other flow processing across the non-Primary cluster nodes. I assume this information is saved someplace within the JVM as it runs, because it is displayed in the Cluster page information. Thank you for any guidance you can provide.
