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 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.
table
Performs functions related to MapR-DB tables.
table upstream
Performs functions related to upstream sources for table replication.
This section provide information about how to organize and manage data using volumes, a unique feature of MapR clusters.
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.
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.
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.
Each command reference page includes the command syntax, a table that describes the parameters, and examples of command usage.
Verifies given user roles for ACEs exists in the /opt/mapr/conf/m7_permissions_roles_refimpl.conf file.
/opt/mapr/conf/m7_permissions_roles_refimpl.conf
Describes the acl commands used to access control lists (ACLs).
Describes the alarm commands that perform functions related to system alarms.
Describes commands used to audit operations related to cluster management and data access.
Describes commands used to blacklist and to list blacklisted users.
Manages cluster features, gateways, and cluster-wide settings.
Manages configuration values for the MapR cluster.
Displays a summary of information about the cluster.
Describes command for working with disks.
Returns key information about volumes, containers, storage pools, and MapR cluster services for debugging and troubleshooting.
Manages entities (users and groups).
Displays information about MapR-DB or file-system components that are identified by a FID.
Manages Hadoop jobs running on the cluster.
Manages MapR licenses.
Refreshes NFS exports and server cache.
Manages nodes in the cluster
Manages resource usage limits for the cluster.
Manages schedules.
Lists all services on the specified node, the memory allocated for each service, the state of each service, and log path for each service.
Sets log level on individual services.
Manages stream functionality.
table create
Creates a new MapR-DB binary or JSON table.
table cf
Manages column families for MapR-DB tables.
These maprcli commands are used to create and manage Change Data Capture (CDC) changelogs. A changelog is used to establish a relationship between a MapR-DB source table (JSON or binary) and a MapR-ES stream topic and to manage the propagation process.
table delete
Deletes a MapR-DB binary or JSON table.
table edit
Edits the attributes of a MapR-DB binary or JSON table.
Manages indexes for MapR-DB JSON tables.
table info
Displays information about a MapR-DB binary or JSON table, or an index on a JSON table.
table region
Manages table regions for MapR-DB binary and JSON tables.
table replica
Performs functions related to replication of MapR-DB binary and JSON tables. Replication occurs for binary-to-binary tables and JSON-to-JSON tables.
table upstream add
Adds a binary table as upstream source for a replica.
table upstream list
Lists the binary tables that replicate data to the specified replica binary table.
table upstream remove
Un-registers a binary table as an upstream source for a replica.
Lets you view and modify the trace buffer, and the trace levels for the system modules.
Displays the status page URL for the specified service.
Manages virtual IP addresses for NFS nodes.
Manages volumes, snapshots and mirrors.
