- Installing MapR and MapR Ecosystem Components
  Describes how to install MapR software and ecosystem components with or without the MapR Installer.
  - MapR Repositories and Packages
    Describes the repositories for MapR software and the ecosystem components.
  - Preparing Each Node
    Defines minimum requirements for 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 Package Key
      Before you install MapR packages, you must install the package key.
    - Step 2: Prepare Packages and Repositories
      To install services correctly, each node must have access to the package files.
      - Using the MapR Repository
        This section describes how to make packages available through the MapR repository.
      - Using a Local Repository
        This section describes how to make packages available through a local repository.
        Creating a Local Repository on RHEL, CentOS, or Oracle Linux
        This section describes how to create and use a local repository.
        Add the repository on each node
        Each node must contain your local repository.
        Enable the EPEL repository on CentOS 6.x, RHEL 6.x, or Oracle Linux 6.4 or higher
        This section describes how to download and install the EPEL repository.
        Enable the EPEL repository on CentOS 7.x, RHEL 7.x, or Oracle Linux 7.0/7.1
        This section describes how to download and install the EPEL repository.
        Enable the EPEL repository on CentOS 8.x, RHEL 8.x, or Oracle Linux 8.x
        This section describes how to download and install the EPEL repository.
        Creating a Local Repository on SUSE
        This section describes how to create and use a local repository.
        Creating a Local Repository on Ubuntu
        This section describes how to create and use 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 Cluster Service Packages
      The installation process varies 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 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 enable metering and the display of certain metrics by the Control System, you must install collectd and OpenTSDB components. Metrics monitoring is part of MapR monitoring, which also includes log monitoring. MapR Monitoring components are available as part of the Ezmeral Ecosystem Pack (EEP) that you selected for the cluster.
    - Step 9: Install Log Monitoring
      Installing the MapR monitoring logging components 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 Ezmeral Ecosystem Pack (EEP) that you selected for the cluster.
    - Step 10: Install Ecosystem Components Manually
      You can install one or more ecosystem components from any Ezmeral Ecosystem Pack (EEP) that is supported by the MapR cluster version. An EEP 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
    Describes post-installation configuration tasks for MapR clusters.
- Installing the File Migration Service on the Edge Cluster
  Describes how to install the File Migration service on CentOS nodes.
- Installing the MapR XD Distributed File and Object Store
  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 and install the MapR Container Storage Interface (CSI) Storage Plugin and the MapR Data Fabric for Kubernetes FlexVolume Driver.
- Installing MapR in the Cloud
  Provides an overview of MapR cloud installer capabilities.
- Installing Metering
  This section describes how to install Metering by using the MapR Installer or manual steps.
- Upgrading MapR Core or EEP Components
  Depending on your current configuration, you may choose to upgrade the release version (core), ecosystem components, clients, or monitoring components.
- Setting Up Clients and Services
  Describes how to set up and use interfaces to an cluster from a client computer.
- Setting Up the Control System
  Describes how to configure and access the Control System.
- Migrating to MapR
  Provides instructions for migrating business-critical data and applications from an Apache Hadoop cluster to a MapR cluster.
- Applying a Patch
