Introducing Ambari administration

Apache Ambari enables you to provision, manage, and monitor your Hadoop cluster.

Installing Ambari creates the default user admin/admin. This Ambari-level administrator user, or Ambari Admin, has full control over all aspects of Ambari, including all clusters managed by the Ambari instance, as well as the abilities to create a cluster, and manage users, groups, and clusters. When you log in to Ambari as Ambari Admin, you can perform all tasks that require permissions of the Ambari Administrator role.
