Reference parameters within execute script processor?

[Carson Goff <Ca...@octo.us>]

Hello,

I have been doing some research lately and have not been able to find anything regarding this. I would like to be able to reference some of my parameters within an execute script processor running a python script, is this currently possible within nifi? If not, is it a planned feature?

Thanks,

 Hi Carson,

Yes, it is possible. You want to add dynamic (user-defined) properties in
the processor config that reference your parameters.

For ExecuteScript [1] these will be passed to your python script as
variables with the same name.
For ExecuteStreamCommand [2] these will be passed to your python script as
environment variables with the same name.

Apache NiFi recently added the ability to reference Sensitive Parameters
from dynamic properties, so even those can be passed to scripts using this
method.

Hope this helps!
