Matt Burgess commented on NIP-1:
--------------------------------
I'd like to revisit this and get it out for a vote. According to the NIP
process it shouldn't need commitment for the work, otherwise only engineers
would really be able to submit a NIP. NIP-5 was approved and the PR for the
nifi-api changes was submitted and merged without commitment for the
implementation work, I'd like to do the same for this one. Thoughts?
> Add VerifiableRegistryClient interface to verify Registry Client
> implementations
> --------------------------------------------------------------------------------
>
> Key: NIP-1
> URL: https://issues.apache.org/jira/browse/NIP-1
> Project: NiFi Improvement Proposal
> Issue Type: New Feature
> Reporter: Matt Burgess
> Priority: Normal
> Labels: nifi-api, nifi-registry
>
> Motivation
> To verify basic connectivity from a NiFiRegistryClient to a Registry instance
> Scope
> Add VerifiableRegistryClient interface to verify NiFiRegistryClient
> implementations
>
> Compatibility
> Existing implementations in Apache NiFi will need to implement the verify()
> method, but a default no-op implementation will be offered so as not to
> interrupt compatibility. The no-op implementation should log/report that no
> actual verification was applied.
> Description
> Registry Clients didn't exist when the Verifiable (ControllerService,
> Processor, ReportingTask, ParameterProvider, etc.) interfaces were added.
> Verification
> Implement the verify method for JerseyNiFiRegistryClient (contributed as a
> separate Jira) and run with a live instance, validating that incorrect
> configurations return error message(s) and a correct configuration returns
> success. Fetching the available buckets should suffice for verification,
> whether buckets exist or not.
> Alternatives
> None identified, current behavior does not allow verification of
> NiFiRegistryClient instances
