I was trying to run apache nifi in windows. I am seeing error.

  • What version of Windows? Also does the user running the NiFi process have permissions to get Process IDs from the operating system? – mattyb Dec 12 '22 at 21:34

I had came across the same situation, after runnig .bat file that launches Nifi, it simply did not start and the cmd returned to its initial state.

This solution helped. Try to clear all folders with '*_repository' name.

It's very simple, it also happens to me.

  1. First uninstall JDK 1.8
  2. Install JDK 1.14
  3. set the environment variable for java.
  4. Run again the run-nifi bat file.

Your problem will be resolved.
