----------------------------------------
Hi Bryan, thanks for the suggestion. I realised that I had to restart Nifi
since the initial processor load failed, so after copy pasting the new version
from the M4 docs (while using Nifi 2.0.0-M3) it worked upon restarting Nifi.
For future reference for anyone else who faces this issue:
(From the 2.0.0-M4 python developer guide)
"Therefore, it’s important to ensure that the Processor is in a good working
state before attempting to load it in NiFi. Otherwise, NiFi will need to be
restarted in order to discover the Processor and load it again."

> When trying the example Python extension from here
> (https://nifi.apache.org/documentation/nifi-2.0.0-M3/html/python-developer-guide.html),
> copy-pasted directly into a file called WriteHelloWorld.py in the required
> directory I get the attached error stating:
> TypeError: FlowFileTransform.__init__() got an unexpected keyword argument
> 'jvm'
> The attached err.log file has more details of the error.
> The custom processor WriteHelloWorld does show up in the list and can be
> dragged onto the canvas, but fails to load due to the error above.
