Subject Re: Duplicated processors when using nifi processors dependency
Date Mon, 22 May 2017 05:24:54 GMT
I created a JIRA for the nifi-aws-bundle structure,
https://issues.apache.org/jira/browse/NIFI-3950.

Is there a best practice for the abstract classes like Robert describes?
Are they a better fit for the service API bundle or the processors bundle?
Or does that become irrelevant once the NAR dependencies are aligned and
they can be references as Java libraries?

Thanks,

James
