did you get it to work? newer NiFi-Versions (i'm on 1.7) seem to must have a distributed cache service as well for the wait / notify pattern

Hi all, i would like to execute a python script which manipulates a .csv or a .json file. in the python file i am using pandas function pd.read_json to read a json file and then to export another one. when this script is ready, i want nifi to get the new json-file and do something else without python (this is already working). the error in nifi is:"no module named pandas" is it possible to use libraries like sklearn and pandas? what is the best practice here? thanks for your help --k

hi Matt, thank you for the tutorial-series. can you maybe show an example how to return in Jython? typing "return FlowFile" leads to an error: javax.script.ScriptException: SyntaxError :'return' outside function in script.

hi Timothy, can you explain this a bit? is it possible to execute a script.py with #!/usr/bin/python inside and then run it as a bash with NiFi? Or how ist this possible to wrap python in a shell? would help me a lot to start my python scripts with sklearn / numpy / pandas inside NiFi, then grab the exports.csv or exports.json and go ahead with my NiFi worlkflow for FlowFiles. cheers
