This Ansible Playbook helps setting up Hortonworks Hadoop Cluster with ease.

You can find installation instructions here for a variety of platforms. Most users should probably install a released version of Ansible from pip, a package manager or our release repository. Officially supported builds of Ansible are also available. Some power users run directly from the development branch - while significant efforts are made to ensure that devel is reasonably stable, you're more likely to encounter breaking changes when running Ansible this way.
