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.
6.1 MapR Data Platform
MapR Data Platform is the industry-leading data platform for AI and analytics that solves enterprise business needs.
6.1 Administration
This section describes how to manage the nodes and services that make up a cluster.
- Administering Users and Clusters
  Lists topics that help manage a MapR cluster.
  - Managing Users and Groups
    Provides a brief introduction to user management on a MapR cluster.
    - Setting Up Email Addresses
      Describes how to set up email addresses using the Control System and the CLI.
    - Setting Up SMTP
      Describes how to set up SMTP information using the Control System and the CLI.
    - Managing Permissions
      Provides an overview of managing user permissions at the cluster, volume and file system levels.
  - Managing the Cluster
    Lists the settings for managing the MapR cluster.
- Administering Nodes
  Provides a synopsis of managing nodes in a cluster.
- Administering Volumes
  This section provide information about how to organize and manage data using volumes, a unique feature of MapR clusters.
- Administering Files and Directories
- Administering Tables
  Administration of the MapR Database is done primarily via the command line (maprcli) or with the Managed Control System (MCS). Regardless of whether the MapR Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. MapR Database administration is associated with tables, columns and column families, and table regions.
- Administering Streams
- Administering MapR Gateways
  A MapR gateway mediates one-way communication between a source MapR cluster and a destination cluster. You can replicate MapR Database tables (binary and JSON) and MapR Event Store For Apache Kafka streams. MapR gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.
- Administering Services
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring Security
  Describes how to configure security and manage secure clusters.
- Managing Secure Clusters
  Provides procedures that will enable you to use MapR clusters securely.
- Administering the MapR Data Access Gateway
  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. This section describes considerations when upgrading the service, how to modify configuration settings, and how to administer and manage the service.
- Planning for High Availability
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
- Troubleshooting Cluster Administration
  Lists the common errors and their solutions.

Setting Up SMTP

Describes how to set up SMTP information using the Control System and the CLI.

About this task

You can specify SMTP server information for the cluster using the Control System and the CLI.

Setting Up SMTP Using the Control System

About this task

Use the following procedure to configure the cluster to use an SMTP server to send email:

Procedure

Log in to the Control System and click Admin > User Settings > SMTP.

Set up the email account the MapR cluster must use to send alerts and other notifications.

Provider	Select Gmail, Office 365, or SMTP from the drop-down menu. If you select Gmail or Office 365, the SMTP server and port information will be pre-filled for you.
SMTP Server	The SMTP server to use for sending mail.
This server requires an encrypted connection (SSL)	Specifies an SSL connection to SMTP.
SMTP Port	The SMTP port to use for sending mail.
Sender's Full Name	The name that MapR should use when sending email. Example: `MapR Cluster`
Sender's Email Address	The email address that MapR should use when sending email.
Sender's Username	The user name that MapR should use when logging on to the SMTP server.
Sender's SMTP Password	The password that MapR should use when logging on to the SMTP server.

Click Save Changes.
An email request is sent to the specified email address. You can check the /opt/mapr/logs/cldb.log file if there is a problem sending the email. If there is a problem, also check the fields to make sure that the SMTP information is correct. Click Revert if you wish to cancel the changes.

Setting Up SMTP Using the CLI

About this task

Use the maprcli config save command to set the SMTP server. For example:

maprcli config save -values '{"mapr.smtp.provider":"gmail",
               "mapr.smtp.server":"smtp.gmail.com",
               "mapr.smtp.sslrequired":"true",
               "mapr.smtp.port":"465",
               "mapr.smtp.sender.fullname":"Ab  Cd",
               "mapr.smtp.sender.email":"xxx@gmail.com",
               "mapr.smtp.sender.username":"xxx@gmail.com",
               "mapr.smtp.sender.password":"abc"}'
