Subject Re: Unable to update processor...

you want to look at the nifi app log and bootstrap logs at startup.

Nifi discovers, unpacks and the loads the NARS at startup. If you aren’t
seeing your custom processor there then that process, that is in the logs
will show what is going on.

I have a custom processor that I have updated (in potentially breaking
ways and I know it), but I cannot seem to make NiFi 1.10.0 open its
mouth and swallow it. I have copied my NAR file to /1.10.0/custom-lib/;
there is no other version (in the /lib/ subdirectory for example). When
I bounce NiFi I see nothing of the changes (properties wording, etc.).
I've been away from NiFi for a while; maybe I'm forgetting something. I
found some artifacts in /1.10.0/work/nar/extensions/ and
/1.10.0/work/docs/ which I removed before bouncing NiFi, but when it
comes back up, all that stuff appears to have been brought back. What am
I missing? Any suggestions of where to look would be welcome.
