MapR 5.1 is at End of Life (EOL) and no longer supported. Please see the latest documentation. This documentation is not being updated.

5.1 Installation
This section provides information for installing with or without (manual) the MapRInstaller, installing patches, upgrading, and migrating.
- Get Started: Install MapR
  The MapR Installer makes the installation of a MapR cluster easy. It installs MapR software after it takes you through the process of selecting services and configuring the cluster.
- Installation Guide
- Upgrade Guide
- Applying a Patch
  MapR patches are version-specific and cumulative. Each patch contains the code fixes that were included in the previous patch for that MapR version.
- Migration Guide

Preparing Each Node

Each node contributes to the cluster, so each must be able to run MapR and Hadoop software.

	Requirements
CPU	64-bit
OS	RedHat, Oracle Linux, CentOS, SUSE, or Ubuntu
Memory	8 GB minimum, more in production
Disk	Raw, unformatted drives and partitions
DNS	Hostname, reaches all other nodes
Users	Common users across all nodes; passwordless ssh (optional)
Java	Must run Java
Other	NTP, Syslog, PAM

Use the subsequent sections as a checklist to make each candidate node suitable for its assigned roles. Once each node has been prepared or disqualified, install MapR software.
