Ambari
======

Apache Ambari is a web application for installing, managing, and monitoring
Apache Hadoop clusters.
The set of Hadoop components that are currently supported by Ambari includes:

Apache HBase
Apache HCatalog
Apache Hadoop HDFS
Apache Hive
Apache Hadoop MapReduce
Apache Oozie
Apache Pig
Apache Sqoop
Apache Templeton
Apache Zookeeper

Ambari's primary audience is system administrators responsible for managing
Hadoop clusters.

Ambari allows them to:

Easily Install a Hadoop Cluster
Ambari provides an easy-to-use, step-by-step wizard for installing
Hadoop services across any number of nodes.
Ambari leverages Puppet to perform installation and 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 Ganglia to render graphs.
Ambari sends email alerts when your attention is needed (e.g., a node
goes down, remaining disk space is low, etc).
Ambari leverages Nagios to monitor and trigger alerts.

In the future, Ambari will allow third-party tool developers to integrate
Hadoop cluster management and monitoring capabilities via its RESTful interface.
