Re: get access token inside custom processor

[Andy LoPresto]

Suraj,

There is no concept of a “logged in user” in NiFi. Many (or none) users may be 
accessing the NiFi UI at the same time, but this is completely independent of 
the flow operation. The component state is running/stopped/etc. regardless of 
the user viewing the UI.

Hi,
Is there any way where we can get the USERID  of same as the $hostname{()} and 
${ip()} of a nifi server.

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

Re: get access token inside custom processor

[Bryan Bende]

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
