This is fresh installation of Ambari 2.1 with HDP 2.3. I am using Ambari to install the HDP services. There was typo from my side under Select Stack --> Advance Repository options for red hat 6 OS with HDP 2.3 version the base url is pointing http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.3.6.0. I corrected the location ass per hdp.repo located under /etc/yum.repo.d/ to use http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.3.4.7. However, after correcting the base url location I am still getting same issue.
