-------------------------------------
Assignee: Bryan Rosander
> RPG port discovery should use name only (not UUID)
> --------------------------------------------------
>
> Key: MINIFI-129
> URL: https://issues.apache.org/jira/browse/MINIFI-129
> Project: Apache NiFi MiNiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 0.1.0
> Reporter: Andrew Grande
> Assignee: Bryan Rosander
>
> Consider the following snippet below. My understanding, based on prior
> discussions, was that MiNiFi uses component and connection IDs only
> internally to wire everything together. My logic then was to rename the RPG
> connection ID and update relevant config sections.
> The problem is that MiNiFi properly instantiates the flow, but fails to find
> the RPG port: *failed to communicate with http://example.com/nifi because the
> remote instance indicates that the port no longer exists*. This is not true
> (port is there and the name is valid). However, as soon as I copy/pasted the
> incoming port ID from the cluster into minifi flow and updated it, things
> starting flow correctly.
> It will be a problem when minfii configs are moved from env to env or
> promoted within SDLC, as RPG ports will have different UUIDs every time.
> Proposal: have MiNiFi negotiate based on the port name only, and use
> connection id internally only.
