ambari Cookbook

This cookbook installs Ambari-server and Ambari-agent in order to provision a cluster with the HDP distribution using the Blueprint API.

Requirements

Supporting (or trying to support) the versions Ambari is supporting.

• RHEL, CentOS, and Oracle Linux 5
• RHEL, CentOS, and Oracle Linux 6
• Suse 11

Usage

ambari::server

Just include ambari::server in your node's run_list:

{
  "name":"my_node",
  "run_list": [
    "recipe[ambari::server]"
  ]
}

ambari::agent

Just include ambari::agent in your node's run_list (alll the nodes of your cluster):

The Ambari Server will be automatically detected, but you can override this detection using the attribute node['ambari']['server']['fdqn'].

{
  "name":"my_node",
  "run_list": [
    "recipe[ambari::agent]"
  ]
}

ambari::server

Include ambari::blueprints in your node's run_list. Then configure the blueprints attributes listed below.
