Hi, I'm CLEO! Something exciting is coming to the Community. Stay Tuned!

I'm using Apache NiFi 2.x with Python-based custom processors. I have two different PythonProcessor scripts (in /python/extensions) with different logic. However, NiFi always runs only the first script's logic, even when I configure the second script in a different processor.

  • How can I ensure NiFi runs the correct Python script for each processor?

  • Is there a proper way to structure and load multiple Python processors in NiFi?

  • Any tip to debug or force NiFi to pick the updated script?
