Hi @Michael Bronson

I think the problem originates from the underscore used in the hostname krysve_ci90. Underscores should not be used in hostnames. Any chance you can try this with a different name / alias?

how you can be sure that underscore isnt allow in ambari ckuster installation , where it is wrote ?

@Michael Bronson

I'm not sure it's explicitly documented for Ambari... Can you try without the underscore and see if it works?

@Michael Bronson

Did it work OK without the underscore? I'm curious and hope I didn't make you go through making a new lab for nothing 🙂 let me know if you still have any errors.
