Subject Nifi startup error after I install my first custom processor
Date Fri, 20 Nov 2015 00:53:48 GMT
Well, I finally built my first processor. Was a nice experience. Nice APIs!
This was my first work with Maven and Nifi so, if things look
wrong/strange, please go easy on me. :) The issue is when I copy the NAR
file in the lib directory and restart Nifi, it does not start up. I tried
removing the work directory for a clean start, no joy. If I remove my NAR,
works fine. Wondering if one of you experts would not mind helping me over
this hump because I have no clue what is happening based on the error
message in the log. Seems like some other processor, DetectDuplicate, is
failing to startup when mine is in there?? I pasted the startup log traces
here: My processor code is here: I would be very
grateful for any guidance. It seems like a pretty simple processor so I was
surprised this happened. The code is commented so hope that helps you
easily understand what is going on there. Oh, I started from this very
helpful post (thanks Bryan):
I am running a build of Nifi from the GitHub mirror,
commit 90f6830003b76204e25dec9fafec2488c8bda550.
