Hello, You can run the NCM on the same machine as a node, but they still have to be two separate processes. You would create two copies of the directory where you extracted nifi and set one to be the manager and one to be the node, you'll also have to give them different nifi.web.http.port values.
For the second error, you could try stopping the instance that is the node and remove the flow.xml.gz that is under conf, and then start it again to have it pull the flow from the NCM. -Bryan On Fri, Dec 18, 2015 at 10:50 AM, plj <[email protected]> wrote: > Howdy, > > I'm trying to set up a cluster for the 1st time.
