Ambari local repository error

Hello,

Setting up local as of http://docs.hortonworks.com/HDPDocuments/Ambari-1.7.0.0/Ambari_Install_v170/Usg_Lcl_Rpo/index.html#Item1.1 i manage to create a local repository with Apache on one server, on a second server i want yum to point to first one via ambari.repo :

On ambari.repo there is 2 sections : [Updates-ambari-1.7.0] and [ambari-1.x]

[Updates-ambari-1.7.0] tarballs is available for download : http://public-repo-1.hortonworks.com/ambari/centos6/ambari-1.7.0-centos6.tar.gz
but [ambari-1.x] is not. Ambari.repo needs both : where can we download [ambari-1.x] tarballs ?
Or does [ambari-1.x] is an obsolete repository address that should be removed ?

Thanks.
