6.0 Administration
This section describes how to manage the nodes and services that make up a cluster.
Administering Tables
Administration of the MapR-DB is done primarily via the command 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.
Administering Change Data Capture
This topic covers the MCS and maprcli tools for managing the Change Data Capture (CDC) feature.

6.0 Administration
This section describes how to manage the nodes and services that make up a cluster.
- Administering Users and Clusters
- Administering Nodes
- 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-DB is done primarily via the command 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.
  - Managing Tables
    MapR-DB supports two types of table: binary tables and JSON tables. This section covers how to create, edit, and delete tables, as well as how to set parameter values, display parameter values, grant permissions and access, replicate tables, and more using the MapR Control System and the CLI.
  - Managing Column Families and Columns
    This section covers overviews of column families in binary tables and JSON tables, how to create column families, alter them, delete them, set permissions on them, and set and display parameter values.
  - Managing Table Replication
    This section contains topics about setting up table replication and administering existing replicas.
  - Managing Secondary Indexes
    Describes how to manage secondary indexes, including adding, deleting, and listing indexes, setting up your cluster for querying, and troubleshooting index usage.
  - Administering Change Data Capture
    This topic covers the MCS and maprcli tools for managing the Change Data Capture (CDC) feature.
    - Setting Up CDC
      To set up the Change Data Capture (CDC) feature, the following must exist or be created: a MapR-DB source table (JSON or binary), a MapR-ES changelog stream, a MapR-ES stream topic, and a MapR-DB table changelog relationship between the source table and the destination stream topic.
    - Managing Table Changelogs
      Describes how to manage CDC table changelogs through the MCS and maprcli.
    - Troubleshooting Changelogs
  - Indexing MapR-DB Binary Tables with Elasticsearch
    As of with MapR 6.0, MapR-DB Elastic Search integration capability is deprecated and no longer available in the MapR-DB product.
- 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-DB tables (binary and JSON) and MapR-ES 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 MapR 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
- Best Practices for Backing Up MapR Information

Administering Change Data Capture

This topic covers the MCS and maprcli tools for managing the Change Data Capture (CDC) feature.

The following topics provide information you need to understand the CDC feature, to setup and use CDC and the maprcli commands used to perform tasks.
