I have a Filesystem datasource which is contains thousands of folders and each folder contains a list of comma separated files.  Each file in each directory contains a different schema and the file name criteria is used to create partitioned data sources with the following using the following format:


This creates a datasource based on all the files that start with KEY in its name.  That part is working as expected.  My problem is that I can't do any recipe against that data source.  I tried python, shell and sync recipes and all of the failed with the same error:

	at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048)
	at com.dataiku.dip.security.process.RegularProcess.start(RegularProcess.java:47)

My current recipe is in python and the code is:

# -*- coding: utf-8 -*-
import dataiku
import pandas as pd, numpy as np
from dataiku import pandasutils as pdu

# Recipe inputs


events_CSV = dataiku.Dataset("KEY_CSV")
events_CSV_df = events_CSV.get_dataframe()

# Recipe outputs
events_ORC = dataiku.Dataset("KEY_ORC")

Job fails before printing "Here".

These are the DSS instance settings:
