Ambari Overview

The Apache Ambari project is aimed at making Hadoop management simpler by developing software for provisioning, managing, and monitoring Apache Hadoop clusters. Ambari provides an intuitive, easy-to-use Hadoop management web UI backed by its RESTful APIs.
The set of Hadoop components that are currently supported by Ambari includes:
HDFS, MapReduce, Hive, HCatalog, HBase, ZooKeeper, Oozie, Pig, Sqoop
Ambari enables System Administrators to:
  • Provision a Hadoop Cluster
    • Ambari provides a step-by-step wizard for installing Hadoop services across any number of hosts.
    • Ambari handles configuration of Hadoop services for the cluster.
  • Manage a Hadoop Cluster
    • Ambari provides central management for starting, stopping, and reconfiguring Hadoop services across the entire cluster.
  • Monitor a Hadoop Cluster
    • Ambari provides a dashboard for monitoring health and status of the Hadoop cluster.
    • Ambari leverages Gangila for metrics collection.
    • Ambari leverages Nagios for system alerting and will send emails when your attention is needed (e.g., a node goes down, remaining disk space is low, etc).
Ambari enables Application Developers and System Integrators to:
  • Easily integrate Hadoop provisioning, management, and monitoring capabilities to their own applications with the Ambari REST APIs.
