Subject: (NiFi 1.6) Funnels with no outgoing relationship filling my app log
I just upgraded one of my servers to NiFi 1.6.0. I have a couple of funnels
that just dead end, Flow File's come in but never go anywhere after that.
Mostly I use this for troubleshooting/validation. The inbound relationships all
have expiration times, and it's a quick way for me to inspect the output of a
processor on the fly.
These funnel's are filling up my logs with errors that they can't output to
Relationship '' (see error log below). If I attach the Funnel to another
downstream processor than everything is fine. I went back and tested on my
1.5.0 server and did not see the errors.
I briefly looked through the code, but the bug didn't jump out at me.
