Hi Russell, Thanks for your question.
Yes, working with Controller Services has definitely changed in 1.x compared to 0.x NiFi. Matt Gilman wrote a nice article about how Controller Service scoping was updated in 1.x with the introduction of Multi-Tenant Authorization and also discusses the recent improvements made in NiFi 1.2 to alleviate some of the user confusion around scoping [1]. If you would like to see further details, the parent Jira for the improvements can be found here [2]. I think there is opportunity to improve the Apache documentation we have around this functionality, so I just filed a new Jira [3]. Let us know if you have any more questions. Thanks, Drew [1] https://community.hortonworks.com/articles/90259/understanding-controller-service-availability-in-a.html [2] https://issues.apache.org/jira/browse/NIFI-3128 [3] https://issues.apache.org/jira/browse/NIFI-3911 > On May 16, 2017, at 11:28 AM, Russell Bateman <r...@windofkeltia.com> wrote: > > It appears to me that that, unlike what happened in NiFi 0.x, in 1.x when I > look at controller services via the General menu -> Controller Services, what > I see is totally different from what I see when I configure controller > services for a processor. > > If I use the General menu to set up my controller services, I do not see nor > am I given the option of using them in particular for processors I'm > configuring.
