This section describes how to manage the nodes and services that make up a cluster.
This section contains in-depth reference information for the administrator.
This section contains information about various scripts and utilities.
This section discusses the mrconfig disk commands.
This section provide information about how to organize and manage data using volumes, a unique feature of MapR clusters.
Administration of the MapR Database is done primarily via the command line (maprcli) or with the MapR 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.
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.
This section describes how to monitor the health and performance of a MapR cluster.
Describes how to configure MapR security and manage secure clusters.
Provides procedures that will enable you to use MapR clusters securely.
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.
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.
Describes the syntax and parameters of configure.sh that you run for a number of tasks including setting up MapR client nodes, and configuring services for a node.
configure.sh
Describes how you can use the gfsck command, under the supervision of MapR Support or Engineering, to perform consistency checks and appropriate repairs on a volume, or a volume snapshot.
This section discusses the mrconfig cntr commands that allow you to manage containers and container replicas.
mrconfig cntr
This section discusses the mrconfig dg commands that allow you to configure disk groups.
mrconfig dg
The mrconfig info commands provide information about memory, threads, volumes, containers and other information about the MapR file system.
