26.2. Administration of HDP Services with Ambari on Red Hat Gluster Storage

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 tough task. To help you deal with the complexity, Apache Ambari collects a wide range of information from the cluster's nodes and services and presents them to you in an easy-to-read format. It uses a centralized web interface called the Ambari Web. Ambari Web displays information such as service-specific summaries, graphs, and alerts. It also allows you to perform basic management tasks such as starting and stopping services, adding hosts to your cluster, and updating service configurations.
