  • QUOTE: Cloudera Manager is the industry’s first and most sophisticated management application for Apache Hadoop and the enterprise data hub. Cloudera Manager sets the standard for enterprise deployment by delivering granular visibility into and control over every part of the data hub — empowering operators to improve performance, enhance quality of service, increase compliance and reduce administrative costs.

     Cloudera Manager is designed to make administration of your enterprise data hub simple and straightforward, at any scale. With Cloudera Manager, you can easily deploy and centrally operate the complete Big Data stack. The application automates the installation process, reducing deployment time from weeks to minutes; gives you a cluster-wide, real-time view of nodes and services running; provides a single, central console to enact configuration changes across your cluster; and incorporates a full range of reporting and diagnostic tools to help you optimize performance and utilization.
