Python Processor and relationships

[Ashwini Kumar <ku...@yahoo.com.INVALID>]

I created a Python Nifi Processor just as in the standard python documentation. This is NOT an ExecuteScript processor.I am able to load the python processor in Nifi but when I click the Configure Processor -> Relationships tab, I see no relationships there. This renders the Python processor useless. We cannot forward the resulting flowfile to any other downstream processors. The Error I get when trying to do so is -> "WriteHelloWorld' does not support any relationships.The basic example in the documentation that I am using returns FlowFileTransformResult with a success relationship but this being a scripted language, NIFI may not know in advance what the relationships may be.Am I missing any steps in defining relationships for python processors?Steps:Created python processor in NifiLoaded it in NifiTried to connected it to PutFile processor Got message stating that my Python processor does not define relationships.
Thanks,Ashwini

Hi,

Are you in a position to share the code of your python processor? Did you
implement getRelationships(self) in your processor?
