> We recently upgrade to nifi 2.4.0 from 1.x and have noticed something weird
> about the parameter provider in 2.x. From time to time, for some reason, the
> parameter provider will complain about invalid revision given when fetching
> for parameters with nifi-cli. Specifically we are using
> AzureKeyvaultParameterProvider. And once this happens, the only way to get
> rid of it is the re-creation of the parameter provider.
> See the screenshot

> And it looks like the revision manager was messed up that every time the new
> revision is always one version below, we are running nifi in a standalone
> mode and consecutively triggering of the parameter fetch will constantly get
> the invalid revision(each time the revision is up by 1) until the parameter
> provider is recreated, even restarting nifi won't help. I'm also quite sure
> there is only one person sending request to fetch for parameter and attempt
> to change the parameter provider at the same time so no concurrent operation.
>
> And once this problem happens, fetching parameters from UI also does not
> work, it would just fail silently and the value of the secrets remains
> unchanged.
>
> Also FYI, this never happened in 1.x
>
> Another FYI, if we restart the nifi container, it does not go away, and the
> revision number in the complaint will start over from 0
>
> Still have no idea how to reproduce it though, but will keep trying and log
> the activities in this ticket
