Download cluster blueprints without hosts

Ensure you download the cluster blueprints before you begin the upgrade. The blueprint of your old cluster is used as the template of the new cluster after you transition to Cloudera Manager.

To download the cluster blueprints without hosts, do the following:

curl ${securecurl} -H "X-Requested-By: ambari" -X GET -u ${ambariuser}:${ambaripwd} ${ambariprotocol}://${ambariserver}:${ambariport}/api/v1/clusters/${clustername}?format=blueprint > "${backupdir}"/${clustername}_blueprint_without_hosts_"$(date +"%Y%m%d%H%M%S")".json

where,

securecurl = -k for https

ambariuser = Ambari User Name

ambaripwd = Ambari Password

ambariprotocol = http or https

ambariserver = Ambari Server Name

ambariport = Ambari Port

clustername = The Name of the cluster

backupdir = The folder to download the blueprint
