1. ambari blueprint is alternative of cluster installation through ambari but before proceeding with this step we have to complete prerequisites and start ambari -server ?

>>>> Yes, ambari server needs to be installed and the ambari agents/server needs to be started on all the cluster nodes before starting the Blueprint deployment.

2 What is use of default_password in above ?

  • default_password: Optional field which specifies a default password for all required passwords which are not specified in the blueprint or cluster creation template configurations.
