Hosts confirm failed. Installing using non root user account.

[#1]

Hi...

I have installed and setup ambari as a root user. Then I created a non root user hadoop and gave full sudo priveleges. I have setup ssh passwordless authentication on both my hosts is working fine. When I am running the launch wizard its failing. at confirm hosts with the below error message. Please advise what to do.

I also saw the topic of installing ambari agents as non root user. I tried the

Error Below

Just re-install ambari and a non root user and consequently launch wizard will succeed. The error is very clear the launch is bootstrapping as user root !

Hi...Geoffrey

Thanks for the response. I was choosing automatic host registration on the UI. I changed it to manual and it worked.
