get access token inside custom processor

Hi guys, I'm trying to invoke some nifi rest apis inside my custom
processor, the nifi I'm using is nifi 1.4.0 and it's a 3 node secured
cluster., the username and password are kept inside a ldap server.
I know that in a secured nifi cluster, in order to make any request I need
the access token, my question is how could I get the access token in my
custom processor? Thanks. (I think the token should be
available somewhere after successful login right?)

regards,
ben

Thanks Bryan I got it, I thought the processor would be running as the user
that had logged into the NIFI web UI.

Hello,

Your custom processor would be the same as if you were writing an
external client program.

You would need to provide the processor with a username and password
in the processor properties, and then it would need to make a call to
the token REST end-point.

Processors don't run as the user from the web UI, they run on behalf
of the NiFi framework and have no idea which user started/stopped
them.

Thanks,

Bryan
