When deploying HDP on a cluster having limited or no Internet access, you should provide access to the bits using an alternative method. For more information about setting up local repositories, see Using a Local Repository. Ambari Server by default uses an embedded PostgreSQL database. When you install the Ambari Server, the PostgreSQL packages and dependencies must be available for install. These packages are typically available as part of your Operating System repositories. Please confirm you have the appropriate repositories available for the postgresql-server packages.
