Thanks for the response Bryan, In the step ListHDFS -> RPG(this part only runs on primary node), the question is how do restrict this flow only to the primary node? Because whatever I create in one node is replicated in all the nodes, so when I create an RPG of say node2, its actually has the same flows as the node1 and then it looks like a loop. Actually, flows I have created are kind of complex and can't share it here, but I hope you understand what I am talking about through the diagram attached. I think we have to configure in a way that the primary node flows are not replicated in the slave nodes. Really appreciate your help. nifi-node-flow-replication-confusion.jpg Thanks, Samir ...
