Subject Re: NIFI templates in template folder in sync with templates inside NIFI UI
Date Thu, 14 Sep 2017 17:00:45 GMT

In the 0.x baseline, the templates were stored in the templates directory
that you're referring to. Starting in the 1.x baseline, the templates were
migrated to become part of the flow.xml.gz. In order to support users
upgrading from 0.x to 1.x, templates in the directory are automatically
moved to the flow.xml.gz. If you're looking to automate template
importing/removal, I would recommend using the REST API. If you open up
your browser you should be able to see these requests in action.
Additionally, you can find documentation for them here [1]. The
import/upload endpoints are under Process Groups and the removal endpoints
are under Templates.
