The > node that has all the flow files is the one you will need to Offload in the > next step > # Disconnect and then Offload the node that gets the flow files in Single > Node load balancing > # Reconnect the node > # Run both processors surrounding the load balanced queue -- This message was sent by Atlassian Jira (v8.3.4#803005)
