/root/iot-truck-streaming/stream-simulator/generate.sh Permission denied

Hello,

Trying to setup the NiFi dataflow for the HDF tutorial, interested in the Kafka part but as far as i understand i must first complete the NiFi part.

However the ExecuteProcess processor gives 'Permission denied' error for the generate.sh script:

Even though i ve given all permissions to the whole repo:

Any ideas?

By Default HDF install the NiFi service to run as the "nifi" user. You issue is likely that the nifi user is unable to navigate down that directory tree to the target script.

Try becoming the nifi user (su - nifi) and navigating to the script directory.

Thank you,

Matt
