I have an Ambari cluster that has 12 members, and I want to add another one. All O/S are CentOS 7.9, Ambari 2.7.5, HDP 3.1.5.
The host that I want to add to the cluster can't get to the internet, so I added /etc/yum.repos.d/ambari-hdp-1.repo to it. Contents of that file have entries for HDP, HDP-GPL, and HDP-UTILS on the Ambari master. The directories exist on the Ambari master, and I can browse to them. "yum repolist" on that host lists the repos as expected.
When I invoke the Add New Host wizard, it successfully finds the host and says the SSH key is valid. When I get to the final page of the wizard (right before deploy), it lists the repositories it's going to pull files from. The repo for HDP-GPL shows the HortonWorks (internet) repo instead of the local repo I put in the host's repo file listed above. At this point, I cancel out of the wizard.
What step(s) do I need to take to get that repo changed? Please advise when you can.
Thanks in advance,
