This section contains information on administering the cluster and MapR-DB, configuring Gateways, and configuring and managing particular aspects of the MapR security infrastructure.
This section contains in-depth reference information for the administrator.
This section contains information about various scripts and utilities.
This section describes how to manage the nodes and services that make up a cluster.
This section describes how to monitor the health and performance of a MapR cluster.
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.
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.
Describes tasks for configuring MapR security, managing secure clusters, and administering auditing.
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.
Dynamically set the loglevel to debug a library.
mapr dbshell
The mapr dbshell is a tool for the creation and the lightweight manipulation of JSON tables and documents.
mapr copytable
Copies data from one MapR-DB JSON table to another MapR-DB JSON table.
mapr difftables
Compares the row keys, column families, and field values in two JSON tables. Then, generates two directories that contain sequence files that you can use to merge the rows from the two JSON tables.
mapr difftableswithcrc
This utility uses a cyclic redundancy check to detect differences between sets of rows in the specified MapR-DB JSON tables. Then, for each set of non-identical rows, it performs a detailed comparison. Finally, it generates one or more directories of sequence files. You can use these files either to merge the rows from two MapR-DB JSON tables.
mapr formatresult
Parses a sequence file generated by the difftables utility for JSON tables and converts the results into a format that makes the results easier to understand.
mapr exporttable
mapr importtable
Use these utilities together to export data from JSON tables into binary sequence files, and then import the data from the binary sequence files into other JSON tables. You can also use the mapr importtable utility to import changes that are specified in sequence files output by the mapr difftables utility.
mapr importJSON
Imports one or more JSON documents into a MapR-DB JSON table. The JSON documents must be flat text files.
This section contains reference information about various configuration files.
