Matt Gilman commented on NIFI-2940:
-----------------------------------
[~aldrin] [~msclarke] In order to purge history, the user needs write
permissions to the Controller. Rather than denying access when the underlying
component is missing, we could allow access when the user has read permissions
to the Controller. Thoughts?

> Key: NIFI-2940
> URL: https://issues.apache.org/jira/browse/NIFI-2940
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.0.0
> Reporter: Aldrin Piri
> Priority: Minor
>
> I have an unsecured instance of NiFi running a fairly standard flow.
> Upon deleting a connection I had wanted to see what relationships were
> attached to it, and viewed the Flow Configuration History. In that listing,
> while I could see that there was an event that took place, all of the details
> were listed as unauthorized.
> I additionally tested with other components (processors, funnels, etc) and
> noted similar results.
