Hi What is the preferred method to alter a nifi processor configuration please? We want to be able to get a user to choose from one of 3 options from a drop down menu in a GUI screen. The chosen option then is passed to either a curl command to make changes to the processor via the Nifi API, or can we create a python command to then alter a nifi processor configuration possibly by curl, but maybe there is another way? Curl looks a safer option, but python might be better? Not sure....? Thanks in advance.  ... View more

When I try to run a query against the nifi 2.5.0 API to get info about provenance activities, it seems to be quite difficult. I installed NIfi on my PC with no modifications and all default settings, and just use the default user and password that's created when you install it. I run this in my local windows CMD window and get   "unknown error" : curl --insecure -X DELETE -H "Authorization: Bearer <my token> " https://localhost:8443/nifi-api/provenance/queries Then I run this and get :  curl --insecure -X DELETE -H "Authorization: Bearer <token>" https://localhost:8443/nifi-api/provenance/queries > test.txt In text.txt file I get : "An unexpected error has occurred. Please check the logs for additional details." I'm starting to think the Provenance part of the API might be broken as it shouldn't be this hard? I ran other API queries and they work fine. What I'm trying to do is get a list of all files that have passed through my small local nifi installation so we can track what files have moved through nifi and when, as a form of monitoring. Any help appreciated! Thanks in advance.   ... View more
