RHEL7.2, Installing HDP 2.5.3, Ambari GUI tells that the URL

http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.5.3.0 is INVALID

BaseURL taken from https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.2.0/bk_ambari-installation/content/hdp_25_repos...

The node has net connection

any idea?

You will need to register a new version first.

Are you defining the "Name" properly in the ambari UI while registering a new HDP 2.5 version?

Ambari UI --> Admin (Tab) --> 'Stack and Versions' --> "Versions" (tab) --> "Manage Version" (Button) --> "Register Version" --> From drop down button choose "HDP 2.5 Default Version Definition"

Then on the right side of this page you will see "Name: HDP-2.5." there you should define the version as 3.0 as mentioned in the screenshot.

.

Now you should be able to install a cluster on this newly register version.

@joe john

Have you checked trying to wget http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.5.3.0/hdp.repo from the server? It could be a case of firewall issues.

Also, can you post what error is shown next to the red exclamation?

Thanks guys. The instructions for setting proxy for ambari is incorrect or not very clear. I got it going and everything was fine.
