How do I get repository credentials

[#1]

I use HDP 3.1.4 and ambari 2.7.4.0

When adding a data node, the following error occurs.

failure: repodata/repomd.xml from ambari-2.7.4.0: [Errno 256] No more mirrors to try.
http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.4.0/repodata/repomd.xml: [Errno 14] HTTP Error 403 - Forbidden

What do i do?

Thank you.

@mdp Cloudera has changed the location of public binaries to implement the paywall. You can get more Information here on theses threads:

To resolve the issue you have to generate the credentials to download the repo behind the Paywall and configure accordingly. 

To identify your authentication credentials using your license key file, complete the following steps:
1. From cloudera.com, log into the cloudera.com account associated with the CDP Private Cloud Base license and subscription agreement.
2. On the CDP Private Cloud Base Download page, click Download Now and scroll down to the Credential Generator.
3. In the Generate Credentials text box, copy and paste the text of the “PGP Signed Message” within your license key file and click Get Credentials. The credentials generator returns your username and password.
