How does Ambari server knows to look for local yum repository

[#1]

Hi, I have created a local yum repository that contains the Ambari, HDP and HDP utils tars extracted as per the documentation After installation of ambari-server and setting it up during start of ambari-server it throws a error

ERROR [main] StackContext:217 - Could not load repo results
java.net.UnknownHostException: public-repo-1.hortonworks.com

How do i tell ambari-server to look in to my local yum repository instead of trying to resolve the internet repo.

How does ambari-server knows to look into local yum and not the internet repo without being explicitly configured somewhere

[#3]

The repos are explicitly defined by an ambari stack. For the HDP stack, these are public-repo-1.hortonworks.com.

You can reconfigure these yourself by logging into Ambari as an admin, dropping down the username > Manage Ambari > Versions > Version Name.

See in the screenshot that I have set the repos to be Artifactory.

My question was during startup of ambari-server itself i am getting the error, so before starting ambari-server should i configure somewhere.

Also if i give local repository details during step 1 (select versions) of Ambari installation wizard it gets stuck at confirm host steps even though both the hosts registered successfully.

when i check the logs it says :

I don't think the message "Unable to lookup the cluster by ID" has anything to do with local repositories, that looks like a problem with how you named your cluster. See "clusterName=clusterID=-1".

But yes, you had to first create an "ambari.repo" and "hdp.repo" file in /etc/yum.repos.d/ that point to your local repo before you even can install ambari-server and other related HDP packages on that machine.
