Apache Ambari

Ambari enables system administrators to provision, manage and monitor a Hadoop cluster, and also to integrate
Hadoop with the existing enterprise infrastructure.

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.

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 Ambari Metrics System for
metrics collection.
Ambari leverages Ambari Alert Framework for
system alerting and will notify you when your attention is needed (e.g., a node goes down, remaining disk space is low, etc).
