• Note: You will now need to set the following env vars with your Cloudera paywall credentials: username paywall_password

• Bring up 4 VMs imaged with RHEL/CentOS 6.x (e.g. node1-4 in this case)

• On non-ambari nodes (e.g. nodes 2-4), install ambari-agents and point them to ambari node (e.g. node1 in this case)

export ambari_server=node1
export ambari_version=2.7.5.0
export username=myuser
