| 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. |
