About MapR 6.1
This site contains the main documentation for Version 6.1 of the MapR Converged Data Platform, including installation, configuration, administration, and reference information.
6.1 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 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.
    - 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.

Installing MapR Data Access Gateway

This topic includes instructions for using package managers to download and install the MapR Data Access Gateway from the EEP repository.

Prerequisites

For instructions on setting up the EEP repository, see Step 10: Install Ecosystem Components Manually.

The MapR Data Access Gateway is included in EEP repositories beginning with EEP 5.0.0. The MapR Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the MapR cluster. For EEP 6.0.0, the MapR Database JSON REST API and Python OJAI client use this service.

In the MapR Installer, the gateway is not visible as a unique service but is installed when the MapR DataBase service is selected and can also be installed manually using this procedure. The gateway should be installed on at least two nodes, if possible, but not on CLDB or Zookeeper nodes. It is recommended to install the service on the same node as the gateway server.

About this task

Run the following commands as root or using sudo.

Procedure

Install the MapR Data Access Gateway package:

On Ubuntu:

apt-get install mapr-data-access-gateway

On RedHat/ CentOS:

yum install mapr-data-access-gateway

On SLES:

zypper install mapr-data-access-gateway

Run configure.sh -R:
```
/opt/mapr/server/configure.sh -R
```
NOTE As the MapR Data Access Gateway is managed by Warden, you don't have to restart Warden after installing the gateway. Warden brings up the service after a few minutes.

What to do next

To manage and administer the gateway, see Administering the MapR Data Access Gateway.

To learn more about the gateway, see Understanding the MapR Data Access Gateway.
