MapR 5.2 Documentation

5.2 Cluster Administration
This section contains information on administering the cluster and MapR-DB, configuring Gateways, and configuring and managing particular aspects of the MapR security infrastructure.
- Administering the Cluster
  This section describes how to manage the nodes and services that make up a cluster.
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring and Managing MapR Gateways
  A MapR gateway mediates one-way communication between a source MapR cluster and a destination cluster. MapR-DB tables and MapR Streams streams can be replicated.
- Administering MapR-DB
  Administration of the MapR-DB is done primarily via the commmand line (maprcli) or with the MapR Control System (MCS). Regardless of whether the MapR-DB table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. MapR-DB administration is associated with tables, columns and column families, and table regions.
- Configuring Security
  Describes tasks for configuring MapR security, managing secure clusters, and administering auditing.
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
  - maprcli and REST API Syntax
    This section provides information about the MapR command API. Most commands can be run on the command-line interface (CLI), or by making REST requests programmatically or in a browser.
  - Utilities
    This section contains information about various scripts and utilities.
  - Configuration Files
    This section contains reference information about various configuration files.
  - Alarms Reference
    The pages in this section provide details about all of the types of alarms.
  - MapR Environment
    This section provides information associated the MapR environment.
    - MapR Parameters
    - Default MapR Configurations
    - Environment Variables
    - Ports Used by MapR
      This page provides two reference tables - one for cluster ports with default port numbers and the other with destination and source details- and tips for avoiding port conflicts.
    - Log Files
- Glossary
  This section contains defintions for commonly used terms in MapR Converged Data Platform environments.
