Hi Björn,
thank you for your reply. I am using both, Knime and the python script from the local machine. As you can see from the script, i am directly addressing the data node port on 50070.
I also tried to use the ports directly (50070 and 50010) in Knime but both resulted in an error. HDP is running in a Virtual Box environment. Is there a special port mapping that Knime requires (and python doesn’t)?
Regards
Ingo
