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.
  - MapR Repositories and Packages
    Describes the repositories for MapR software and Hadoop Ecosystem tools.
  - Preparing each Node
    Identifies major factors in preparing each node in your cluster.
  - Installing with the MapR Installer
    The MapR Installer automates the process of installing MapR software and offers you a variety of options to complete the installation.
  - Installing without the MapR Installer
    Describes how to install MapR software and ecosystem components manually.
    - Step 1: Install the MapR Package Key
      Before you install MapR packages, you must install the MapR package key.
    - Step 2: Prepare Packages and Repositories
      In order to correctly install services, each node must have access to the package files.
      - Using the MapR Internet Repository
        This section describes how to make packages available through the MapR internet repository.
      - Using a Local Repository
        This section describes how to make packages available through a local repository.
      - Using a Local Path with rpm or deb Package Files
        This section describes how to make packages available through a local path.
    - Step 3: Install MapR Service Packages
      The installation process will vary based on the location of your packages and the configuration of your cluster.
    - Step 4: Verify Installation Success
      To confirm success, check each node.
    - Step 5: Set Environment Variables
      Before starting ZooKeeper or Warden, you must complete this step.
    - Step 6: Configure Nodes
      Connect nodes to the cluster, configure security, and arrange node storage.
    - Step 7: Bring up the Cluster
      Before you can install metrics monitoring, log monitoring, or ecosystem components, you must enable the cluster by starting ZooKeeper and Warden and verifying the cluster installation status.
    - Step 8: Install Metrics Monitoring
      To provide metrics monitoring, the MapR Control System (MCS) requires the collectd and OpenTSDB components to be installed. Metrics monitoring is part of MapR Monitoring, which also includes log monitoring. MapR Monitoring components are available as part of the MapR Ecosystem Pack (MEP) that you selected for the cluster.
    - Step 9: Install Log Monitoring
      Installing the logging components of MapR Monitoring is optional. The logging components enable the collection, storage, and visualization of MapR Core logs, system logs, and ecosystem-component logs. MapR Monitoring components are available as part of the MapR Ecosystem Pack (MEP) that you selected for the cluster.
    - Step 10: Install Ecosystem Components Manually
      You can install one or more ecosystem components from any MapR Ecosystem Pack (MEP) that is supported by the MapR cluster version. A MEP consists of a group of ecosystem components that work together.
    - Step 11: Run configure.sh
      Run configure.sh with the -R option to complete the configuration of ecosystem components that were added manually.
  - Configuring the Cluster
    This section contains information on configuring MapR clusters.
- 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.
- 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.

Step 2: Prepare Packages and Repositories

In order to correctly install services, each node must have access to the package files.

The MapR software distribution is separated into two repositories that contain the package files:

MapR packages. These provide core functionality for MapR clusters, such as the MapR file system.
MapR ecosystem packages. These packages are not specific to MapR. Examples include the packages for Hive and Pig.

You can make packages available to each node, as described in subsequent sections, using the MapR internet repository, a local repository, or a local path with rpm or deb package files. For information about packages and repositories for MapR software and Hadoop Ecosystem tools, see MapR Repositories and Packages.
