Installer Stanzas

This section describes how to prepare for and use Installer Stanzas to install, upgrade, or uninstall software.

Installer Stanzas enable API-driven installation of data-fabric clusters. An extension of the Spyglass Initiative, Installer Stanzas enable the creation of a YAML configuration file (a "Stanza") that describes a cluster. A command-line addition to the web-based Installer allows you to execute the configuration file programmatically to automate new deployments.

You can use Installer Stanzas when you need a script-based tool to install MapR software and you do not want to click through the menus and options provided by the Installer. Installer Stanzas provide less visual feedback than the Installer, but they can be faster and more efficient at installing software on clusters with many nodes.

To use Installer Stanzas:

Review the Installer Stanza Prerequisites.
Use the steps in Installer to download and run the mapr-setup.sh script. Performing these steps installs both the web-based Installer and the Installer Stanzas feature.
Review or edit the Stanza file. The Stanza file specifies the installation parameters for your cluster. See Working with Installer Stanza Files.
Run the Installer Stanza file. See Running Installer Stanza Files.
