Subject Re: New to NiFi and interested on clustering capabilities

That section is still incomplete unfortunately. We are definitely pushing
the documentation at the moment. Personally, I am working through getting
our REST endpoints documented. I know another committer has been working on
the contribution guide as well some introduction to NiFi quick start
guides. I can provide some quick points here in the meantime.

In the section for web properties you'll want to configure the 'https'
properties instead of the 'http' properties.

The further down you'll need to configure the security properties.

These will define the certificates that are used by the web server (and
cluster and site to site communications). You will need to configure all
the keystore properties and truststore properties (if keyPasswd is not
configured the keystorePasswd will be tried as the keyPasswd). If you set
needClientAuth to false, clients will be required to trust the keystore
configured here. User access will still be anonymous however. If you set
needClientAuth to true, clients will need to have certificates loaded in
their browser that are trusted by the truststore configured here. User
access will be considered using the DN from their certificate and the
authorization provider.

NiFi supports pluggable authorization which is only necessary if
needClientAuth is set to true. By default its configured with a file based

Details on setting up this file and controlling the level of access have
started being discussed here [1].

Hope this helps while we get more detailed documentation written up. Thanks.
