Chapter 1. Overview: Ambari User Guide

Hadoop is a large-scale, distributed data storage and processing infrastructure using clusters of commodity hosts networked together. Monitoring and managing such complex distributed systems is a non-trivial task. To help you manage the complexity, Apache Ambari collects a wide range of information from the cluster's nodes and services and presents it to you in an easy-to-read and use, centralized web interface, Ambari Web.

Ambari Web displays information such as service-specific summaries, graphs, and alerts. You use Ambari Web to create and manage your HDP cluster and to perform basic operational tasks such as starting and stopping services, adding hosts to your cluster, and updating service configurations. You also can use Ambari Web to perform administrative tasks for your cluster such as enabling Kerberos security and performing Stack upgrades.

For more information on administering Ambari users, groups and views, refer to Hortonworks Data Platform Apache Ambari Administration.
