3. Select Stack

The Service Stack (the Stack) is a coordinated and tested set of HDP components. Use a radio button to select the Stack version you want to install. To install an HDP 2x stack, select the HDP 2.1 or HDP 2.0 radio button.

Under Advanced Repository Options, you can select the Base URL of a repository from which Stack software packages download. Ambari sets the following, default repository URLs. depending on the Internet connectivity available to the Ambari server host:

  • For an Ambari server host having Internet connectivity, Ambari sets a URL to download the latest patch release for the HDP 2.x stack.

    For HDP 2.1, URLs like: http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/, that download the latest release available for each supported operating system, appears.

    You can override that URL with one like: http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/, that downloads the initial 2.0 release, or one that points to your local HDP 2.0 repository. To review your options for configuring local repositories, see Optional: Configure Ambari for Local Repositories.

  • For an Ambari server host having NO Internet connectivity, the default repository location is set in the stack, to the URL that downloads the latest patch release available at the time Ambari shipped.


If using HDP 2.1.3, the YARN ATS component may fail to start. See the Ambari Troubleshooting Guide for more information.


The UI displays repository Base URLs based on Operating System Family (OS Family). Be sure to set the correct OS Family based on the Operating System you are running. The following table maps the OS Family to the Operating Systems.
