6.0 Installation
This section contains information about installing and upgrading MapR software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a MapR cluster.
Upgrading MapR Core 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 Ecosystem Packs
Describes how to upgrade MapR Ecosystem Packs (MEPs), 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 Ecosystem Pack (MEP) Upgrades
The set of ecosystem components that you run in the cluster must all belong to the same MEP.

MapR 6.0 Documentation

6.0 Installation
This section contains information about installing and upgrading MapR software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a MapR cluster.
- Planning the Cluster
  Describes information and factors used in planning your cluster.
- Installing MapR and/or MapR Ecosystem Components
  Describes how to install MapR software and ecosystem components with the MapR Installer or without the MapR Installer.
- Installing the File Migration Service on the Edge Cluster
- Installing MapR-XD
  Describes how to install MapR-XD software with or without the MapR Installer.
- Installing MapR Data Fabric for Kubernetes
  This section describes how to plan for, install, and upgrade the MapR Container Storage Interface (CSI) Storage Plugin and MapR Data Fabric for Kubernetes FlexVolume Driver.
- Installing MapR in the Cloud
  Provides an overview of MapR cloud installer capabilities.
- Upgrading MapR Core 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 Ecosystem Packs
    Describes how to upgrade MapR Ecosystem Packs (MEPs), 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 Ecosystem 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 MapR Ecosystem Pack
      Complete these pre-upgrade steps for each ecosystem component in the MEP that you want to upgrade.
    - Upgrading the MapR Ecosystem Pack 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 Ecosystem Pack (MEP).
    - Upgrading the MapR Ecosystem Pack Without the MapR Installer
      After you upgrade MapR core without using the MapR Installer, you need to upgrade ecosystem components with manual steps. First, verify that your repository is configured to use a MapR Ecosystem Pack (MEP) that is supported by your cluster version. Then, upgrade each component manually.
    - Finishing the MapR Ecosystem Pack Upgrade
      Complete the post-upgrade steps for each ecosystem component that was upgraded.
  - Preparing the Cluster for a Maintenance Update
    This section identifies how to prepare for applying either a minor update or a patch.
  - Performing a Maintenance Update
    Perform a maintenance update when you want to upgrade to a new patch version of MapR Core or apply a patch.
- Setting Up Clients
  Describes how to set up and use interfaces to a MapR cluster from a client computer.
- Setting Up the MapR Control System
  Describes how to configure and access the MapR Control System (MCS).
- 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.

Planning MapR Ecosystem Pack (MEP) Upgrades

The set of ecosystem components that you run in the cluster must all belong to the same MEP.

As of MapR 5.2, you must install ecosystem components as part of a MEP. You will be offered packs to install that contain selected component versions. After upgrading, you may want to upgrade to a more recent MEP to get the latest patch releases or newer versions of ecosystem components.

Most MapR core versions support multiple MEPs, but the set of ecosystem components that you run in the cluster must all belong to the same MEP. You cannot selectively upgrade components. When you upgrade a MEP, all components are replaced with the versions contained in the newly selected MEP.

For details on the ecosystem components available in each MEP and the list of MEPs supported by your MapR cluster version, see the MEP Release Notes.

For API or behavioral changes associated with new ecosystem components, see the documentation for the individual component under Ecosystem Components.
