NiFi - restricted processors won't start (REST-API, NiFi Toolkit)

justenji — Fri, 16 Sep 2022 14:32:22 GMT

I have a process-group which has to be started via rest-api.

Principial it works to start the process-group but processors inside which are marked as "restricted" won't get started, f.e. ExecuteScript, PutFile. These processors remain stopped. No error message. In nifi-app.log are only the started processors listed. No word of the others.

In the UI of course I can start these processors.

How to solve this via rest-api? Thanks for any help.

Using NiFi 1.9.2

SUPPLEMENT

It is not a REST-API thing.

Tried with NiFi Toolkit (/bin/cli.sh nifi pg-start -pgid 708358fc-016c-1000-0000-00000bf....). All processors get started excepted the restricted ones.

So where is the cause and how to fix this?

Solved
Cluster-node users (who obviously execute these actions via rest-api or toolkit cli) had no permission to work with restricted components.
Added permission, startet NiFi new and it works.

Would by helpfull if somewhere a message would come up to tell that this is an authorization problem...
