Chapter 2. Using a Local Repository
If your enterprise clusters have limited outbound Internet access, you should consider using a local repository, which enables you to benefit from more governance and better installation performance. You can also use a local repository for routine post-installation cluster operations such as service start and restart operations. Using a local repository includes obtaining public repositories, setting up the repository using either no internet access or limited internet access, and preparing the Apache Ambari repository configuration file to use your new local repository.
