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 HPE Ezmeral Data Fabric Database tables.
table region
Manages table regions for HPE Ezmeral Data Fabric Database binary and JSON tables.
Lists topics that help manage a data-fabric cluster.
Provides a synopsis of managing nodes in a cluster.
This section provide information about how to organize and manage data using volumes, a unique feature of HPE Ezmeral Data Fabric clusters.
Administration of the HPE Ezmeral Data Fabric Database is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the HPE Ezmeral Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Ezmeral Data Fabric Database administration is associated with tables, columns and column families, and table regions.
A data-fabric gateway mediates one-way communication between a source data-fabric cluster and a destination cluster. You can replicate HPE Ezmeral Data Fabric Database tables (binary and JSON) and HPE Ezmeral Data Fabric Event Store streams. Data Fabric 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 HPE Ezmeral Data Fabric Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the HPE Ezmeral Data Fabric 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.
Lists configuration values for the data-fabric cluster.
Displays a summary of information about the cluster.
Lists disk parameters.
Returns key information about volumes, containers, storage pools, and MapR cluster services for debugging and troubleshooting.
Manages entities (users and groups).
Displays information about HPE Ezmeral Data Fabric Database or file-system components that are identified by a FID.
Lets you perform tiering operations at the file level.

Sets log level on individual services.
Manages stream functionality.
table create
Creates a HPE Ezmeral Data Fabric Database binary or JSON table.
table cf
Manages column families for HPE Ezmeral Data Fabric Database 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 HPE Ezmeral Data Fabric Database source table (JSON or binary) and a HPE Ezmeral Data Fabric Event Store stream topic and to manage the propagation process.
table delete
Deletes a HPE Ezmeral Data Fabric Database binary or JSON table.
table edit
Edits the attributes of a HPE Ezmeral Data Fabric Database binary or JSON table.
Manages indexes for HPE Ezmeral Data Fabric Database JSON tables.
table info
Displays information about a HPE Ezmeral Data Fabric Database binary or JSON table, or an index on a JSON table.
table region list
Lists the regions that make up a specified table or index.
table region merge
Merges regions of a table together to reduce the number of regions that a table occupies.
table region pack
Manually triggers the packing of regions.
table region split
Splits a region in a table.
table replica
Performs functions related to replication of HPE Ezmeral Data Fabric Database binary and JSON tables. Replication occurs for binary-to-binary tables and JSON-to-JSON tables.
table securitypolicy
Manages security policies for HPE Ezmeral Data Fabric Database JSON tables.
table upstream
Performs functions related to upstream sources for table replication.
Lets you create, modify, remove, and retrieve list of tiers and tiering rules.
Lets you view and modify the trace buffer, and the trace levels for the system modules.
