Bryan Bende updated NIFI-7661:
------------------------------
Status: Patch Available (was: In Progress)
> Improve validation of controller services against the required API
> ------------------------------------------------------------------
>
> Key: NIFI-7661
> URL: https://issues.apache.org/jira/browse/NIFI-7661
> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 1.11.4
> Reporter: Bryan Bende
> Assignee: Bryan Bende
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Currently when we validate a configurable component, we find property
> descriptors that identify controller services, and we validate that that
> selected service matches the required API. This is done by checking that the
> bundle coordinate of the API exists in the bundle hierarchy of the
> implementation. Since this comparison is an exact match on bundle
> coordinates, it doesn't take into account for the scenario where the exact
> bundle dependency was missing, but there was one other bundle with the same
> artifact id so it was auto-selected.
> As an example, if you took the latest NiFi release of 1.11.4 and you added a
> controller service NAR from 1.11.3, such as nifi-dbcp-service-nar, during
> start up the dependency of nifi-standard-services-api-nar 1.11.3 would be
> missing, but nifi would auto-select the same NAR from 111.4. Later if you
> took a processor like ExecuteSQL and selected a DBCPService from 1.11.3, you
> would get a validation error saying that the processor requires the API from
> 1.11.4 but the service implements the API from 1.11.3.
