Re: Importing template into 1.2.0

Tim, Just wanted to provide a few more details. Prior to 1.2.0 the flow and templates did not contain any details about the NAR (bundle) it was packaged in. In 1.2.0, since your template did not contain any bundle details NiFi attempted to find a compatible Processor (matched by class name only).

Re: Queue incoherent state

Sorry for the delayed response. Similar behavior has been reported by some other users [1]. Does the connection have any back pressure threshold configured? Can new flowfiles be enqueued? Do the expiration settings have any affect? Lastly, if you restart the cluster does it claim the connection
