I'm trying to kerberize my cluster. I installed Kerberos 5 server following this guide. Everything there seemed to work. After that I tried to kerberize my cluster following the official documentation, but it fails after testing the Kerberos clients with the following error:
500 status code received on POST method for API: /api/v1/clusters/BIKW/requests
Error message: An internal system exception occurred: Failed to execute the command: Broken pipe
Sadly I couldn't find another post where someone had a similar problem. I attached the log with the complete error stack.
