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.
  - MapR Repositories and Packages
    Describes the repositories for MapR software and Hadoop Ecosystem tools.
  - Planning the Cluster
    Describes information and factors used in planning your cluster.
  - 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.
    - 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
      Arrange node storage, and connect nodes to the cluster.
    - Step 7: Bring up the Cluster
      Ensure that you have prepared and validated each node.
    - Step 8: Install Ecosystem Components Manually
      You can install one or more ecosystem components from any MapR Expansion Pack (MEP) that is supported by the MapR cluster version. A MEP consists of a group of ecosystem components that work together.
    - Step 9: Install MapR Monitoring
      After you install the cluster and ecosystem components, you can install MapR Monitoring. MapR Monitoring components are available as part of the MapR Expansion Pack (MEP) that you selected for the cluster.
  - Configuring the Cluster
    This section contains information on configuring MapR clusters.
  - Setting Up the Client
    Describes how to set up and use interfaces to a MapR cluster from a client computer.
- 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.
- 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.

Installing without the MapR Installer

Describes how to install MapR software and ecosystem components manually.

After you have planned the cluster and prepared each node, you can install the MapR distribution from the MapR repository or package files. Installing MapR requires that you perform certain steps on each node. You can install Apache Ecosystem components, such as HBase or Hive after you bring up the cluster.

WARNING: Before you install, make sure that all nodes meet the requirements for installation. See Preparing each Node for more information. Failure to prepare nodes is the primary cause of installation problems.

You must also have the following information from your cluster plan when you install:

A list of the hostnames (or IP addresses) for all nodes and the services that you want to run on each node.
A list of all disks and/or partitions to use on each node.

NOTE: For information about repositories and packages for MapR software and Hadoop Ecosystem tools, see MapR Repositories and Packages.

To successfully install MapR, complete each step described in subsequent sections.
