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.

Planning the Cluster

A MapR Hadoop installation is usually a large-scale set of individual servers, called nodes, collectively called a cluster. In a typical cluster, most nodes are dedicated to data processing and storage, and a smaller number of nodes run other services that provide cluster coordination and management.

The first step in deploying MapR is planning which servers will form the cluster, and selecting the services that will run on each node. To determine whether a server is capable of contributing to the cluster, it may be necessary to check the requirements in Preparing Each Node. Each node in the cluster must be carefully checked against these requirements; unsuitability of a node is one of the most common reasons for installation failure.

The objective of a cluster plan is to detail each node's set of services.
