Introduction to Cloudera Manager Installation
Cloudera Manager automates the installation and configuration of CDH on an entire cluster, requiring only that you have root SSH access to your cluster's machines, and access to the internet or a local repository with installation files for all these machines. Cloudera Manager consists of:
- A small self-executing Cloudera Manager installation program to install the Cloudera Manager Server and other packages in preparation for cluster host installation
- Cloudera Manager wizard for automating CDH installation and configuration on the cluster hosts
- Cloudera Manager features for monitoring and configuring the cluster after installation is completed
Cloudera Manager provides two methods for installing CDH and its associated components: traditional packages (RPMs or Debian packages) or parcels. Parcels are a new packaging format that simplifies the installation process, and more importantly allows you to download, distribute, and activate a new CDH version all from within Cloudera Manager. Parcels are available for CDH (4.1.2 and onwards) and Impala (0.6 and onwards).
