This section provides information about development content including MapR-FS and MapReduce development topics and reference content.
Manages stream functionality.
You can manage MapR-DB tables using HBase shell commands and additional HBase shell commands included in the MapR distribution of Hadoop.
Each command reference page includes the command syntax, a table that describes the parameters, and examples of command usage.
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.
Generates a Nagios Object Definition file that describes the cluster nodes and the services running on each.
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.
stream assign list
For the given stream, lists consumers and the topics and partitions that the consumers are reading messages from.
stream create
Creates a new stream.
stream cursor delete
Deletes committed cursors that are in the partitions in a stream.
stream cursor list
Lists the cursors for the consumers of a stream.
stream delete
Deletes the specified stream. Deleted streams cannot be recovered unless they were previously replicated.
stream edit
Edits the values of parameters for the specified stream.
stream info
Displays the values of the parameters of the specified stream.
stream purge
Runs the purge process, removing messages that are marked for deletion and reclaiming disk space.
stream replica add
Registers an existing stream as a replica of the specified stream.
stream replica autosetup
Sets up and starts replication between a source stream and replica stream.
stream replica edit
Modifies the way in which messages are replicated from one stream to another.
stream replica list
Lists the replicas of a given stream.
stream replica pause
Pauses replication from a source stream to a replica stream.
stream replica remove
Unregisters a stream as the replica of another stream.
stream replica resume
Resumes replication from one stream to another stream.
stream upstream add
Registers a stream as an upstream source for a given stream. For example, if you wanted to replicate messages from Stream_A to Stream_B, Stream_A would be the upstream source for Stream_B.
Stream_A
Stream_B
stream upstream list
Lists all of the streams that are replicating to a given stream.
stream upstream remove
Unregisters a stream as an upstream source for a given stream.
stream topic create
Creates a topic in the specified stream.
stream topic delete
Deletes the specified topic from the specified stream.
stream topic edit
Allows you to increase the number of partitions that are in the specified topic.
stream topic info
Lists information about the partitions in the topics that are in a stream.
stream topic list
Lists the topics that are in a stream, as well as the number of partitions in each topic.
Performs functions related to MapR-DB tables.
Manipulates information about the Hadoop jobs that are running on your cluster.
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.
This section contains defintions for commonly used terms in MapR Converged Data Platform environments.
