I am trying to setup a local repository, and downloaded the HDP 2.5.3 tarball, after untared, the structure looks like HDP/centos6/<components>. Should that be HDP/centos6/2.x/updates/18.104.22.168/<components>? Am I missing something here?
The packaging isn't any different, although the embedded directory structure may not match the public repo. Every company I've worked with that manages local repo's usually has their own directory structure anyhow. You're more than welcome to alter that directory structure to fit your environment.
