MapR 5.2 Documentation

5.2 Installation
This section contains information on installing and upgrading MapR. It also contains information on how to migrate data and applications from an Apache Hadoop cluster to a MapR cluster.
- Installing MapR or MEP Components
  Describes how to install MapR software and MapR Expansion Pack (MEP) components with the MapR Installer or without the MapR Installer.
- Installing MapR-XD
  Describes how to install MapR-XD software with or without the MapR Installer.
- Installing MapR in the Cloud
  Provides an overview of MapR cloud installer capabilities.
- Upgrading MapR or MEP Components
  Depending on your current configuration, you may choose to upgrade the MapR version (MapR Core), ecosystem components, clients, or MapR Monitoring components.
  - Upgrading MapR Core
    Describes the process of upgrading MapR Core.
  - Upgrading MapR Expansion Packs
    Describes how to upgrade MapR Expansion Packs (MEP), either as part of a MapR Core upgrade or to take advantage of a new MEP for the current version of MapR Core.
    - Planning MapR Expansion Pack (MEP) Upgrades
      The set of Ecosystem components that you run in the cluster must all belong to the same MEP.
    - Preparing to Upgrade the MEP
      Complete these pre-upgrade steps for each component in the MapR Expansion Pack (MEP) that you want to upgrade.
    - Upgrading the MEP With the MapR Installer
      If the cluster that you want to upgrade was installed using the MapR Installer, you can use the MapR Installer to upgrade the MapR Expansion Pack (MEP).
    - Upgrading the MEP Without the MapR Installer
      After you upgrade MapR core without using the MapR Installer, you need to upgrade ecosystems components with manual steps. First, verify that your repository is configured to use a MapR Expansion Pack (MEP) that is supported by your cluster version. Then, upgrade each component manually.
    - Finishing the MEP Upgrade
      Complete the post-upgrade steps for each ecosystem component that was upgraded.
- Migrating to MapR
  Provides instructions for migrating business-critical data and applications from an Apache Hadoop cluster to a MapR cluster.
- Applying a Patch
  You can apply a patch by using the MapR Installer, by using the command line (a manual process), or by using a MapR Installer Stanza.

Upgrading MapR Expansion Packs

Describes how to upgrade MapR Expansion Packs (MEP), either as part of a MapR Core upgrade or to take advantage of a new MEP for the current version of MapR Core.

A MapR Expansion Pack (MEP) provides a set of ecosystem components that are fully tested by MapR to be interoperable except where noted. For more information about MEPs, see MapR Expansion Packs.
