George Knaggs commented on NIFI-5029:
-------------------------------------
Thanks Doug and Bryan for looking into issue from the UI that I reported. I
was not able to replicate it outside our HDF install of Nifi 1.7.1. and Nifi
Registry 0.3. I tried to replicate using docker images of Nifi and Nifi
Registry and everything worked perfectly. We’ve since decided to stop using
HDF and move to straight install from Apache distribution.
> CLI - Handling of embedded versioned process groups during export/import
> ------------------------------------------------------------------------
>
> Key: NIFI-5029
> URL: https://issues.apache.org/jira/browse/NIFI-5029
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Flow Versioning, SDLC, Tools and Build
> Reporter: Pierre Villard
> Priority: Major
> Labels: SDLC
>
> I'm in a situation where, in my dev environment, I have a versioned process
> group A in bucket bA containing an embedded process group B from bucket bB.
> Both A and B are versioned in the NiFi Registry of my dev environment.
> I'm using the CLI to export both A and B from my dev Registry, and then
> importing A and B in my prod Registry. The issue is that in the json
> representing A, there is a reference to B containing the url of the dev
> Registry, the bucket ID and the workflow ID representing B.
> To import B in my prod registry, I first created a bucket bB and a workflow
> B. New UUIDs have been generated for both in the prod registry. Then I did
> the import of the JSON representing B.
> Now I manually update the JSON representing A to set the UUIDs related to B
> with the new values of my prod registry. Then I created a bucket and a
> workflow for A in my prod registry, and did the import.
> Problem occurs when I try to import the process group A in my prod NiFi.
> It'll fail with an error looking like this:
> {code:java}
> #> nifi pg-change-version -fv 2 -pgid &1 -u http://localhost:8080
> > Using a positional back-reference for 'A'
> ERROR: Error executing command 'pg-change-version' : Error updating version
> control information: The Flow Registry with ID
> 56a49113-0162-1000-0a7e-4959d312d445 reports that no Flow exists with Bucket
> 9d87ccc4-7084-4069-850a-7704135ea9e9, Flow
> 7e47aeba-4908-41a6-88d7-e6deb1abef98, Version 2{code}
> I guess there are multiple ways of handling it. It could be on the CLI side
> or on the Registry side (could be related to NIFIREG-148).
