ambari
======

The [Apache Ambari][1] project is aimed at making Hadoop management simpler by
developing software for provisioning, managing, and monitoring Apache Hadoop
clusters. [Ambari][2] provides an intuitive, easy-to-use Hadoop management web UI
backed by its RESTful APIs.

Make sure that ambari-server is reachable by ambari-agents via DNS.
