Subject Re: Spark & NiFi question

Hi Conrad,

I think there are a couple of things at play here...

One is that the SSL properties need to be set on the
SiteToSiteClientBuilder, rather than through system properties. There
should be methods to set the keystore and other values.

In a secured NiFi instance, the certificate you are authenticating with
(the keystore used by the s2s client) would need to have an account in
NiFi, and would need to have access to the output port.
If you attempt to make a request with that cert, and then you go into the
NiFi UI as another user, you should be able to go into the accounts section
(top right) and approve the account for that certificate.

Then if you stop your output port, right-click and Configure... and from
the Access Controls tab started typing the DN from your cert and add that
user to the Allowed Users list. Hit Apply and started the port again.

We probably need to document this better, or write up an article about it
somewhere.

Let us know if its still not working.

Thanks,

Bryan
