MapR launched the MapR Installer last year to provide cluster operators an intuitive way to set up a MapR cluster using a step-by-step wizard. The wizard guides you through:
At MapR, we have set up multiple clusters for several of our enterprise customers, and we have brought that knowledge and best practices to MapR Installer. Increasingly, these deployments have not only grown in number, but have also evolved based on the type, purpose, and lifetime of these clusters. If you add to the mix the rapid innovation in the community and the complexity that it brings, there is a clear demand for a higher level of automated and consistent cluster provisioning.
Under the Spyglass Initiative, today we are proud to announce MapR Installer Stanzas. MapR Installer Stanzas enable API-driven installation for the industry’s only converged data platform. With this capability, operators can build a Stanza, which contains layout and settings for the cluster to be installed, and pass it programmatically to the installer to execute the set of instructions.
This new capability is very useful 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 MapR Installer wizard. While this method provides less visual feedback than the GUI version, it can be faster and more efficient at installing software on clusters with many nodes. Not only that, but once a Stanza gets defined, you can automate the cluster setup process for each successive cluster creation with a minimum set of changes.
Read the detailed “how-to” guide here. At the heart of these Stanzas is a YAML file. You must configure a YAML file before using this method to install or upgrade a cluster. Sample YAML files (basic and advanced) can be found in the installer package, but here are the top-level sections:
Here’s an example structure for a 3-node cluster:
environment: mapr_core_version: 5.2.0 config: hosts: - demonode[1-3].example.com ssh_id: root license_type: enterprise mep_version: 2.0 disks: - /dev/sdb - /dev/sdc services: template-05-converged:
MapR Installer Stanzas come with the following set of commands that can be executed on the command line:
