@Anpan K Ambari Server uses Version Definition Files (VDF) to understand which product and component versions are included in a release. The VDF file contains various Operating System and their Repo URLs. VDFs also provides individual components name & version information that are shipped with that verison of product. Example: HDP 2.6.2 (VDF): http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.6.5.0/HDP-2.6.5.0-292.xml Users can also create their own VDFs (by following the same format as mentioned in the above VDF) by editing the <repoid/> tags informations for each repository to match their Local repository OR Satellite/Spacewalk channel names previously configured. VDFs helps in minimizing efforts in registering a new version. It also helps in automated cluster creation specially in case of Blueprints: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-release-notes/content/ambari_relnotes-2.6.0.0-behavioral-changes.html ...
