    You can manage MapR-DB tables using HBase shell commands and additional HBase shell commands included in the MapR distribution of Hadoop.
  - YARN commands
  - maprcli and REST API Syntax
    - Overview
      Each command reference page includes the command syntax, a table that describes the parameters, and examples of command usage.
    - acl
      Describes the acl commands used to access control lists (ACLs).
    - alarm
      Describes the alarm commands that perform functions related to system alarms.
    - audit
      Describes commands used to audit operations related to cluster management and data access.
    - blacklist
      Describes commands used to blacklist and to list blacklisted users.
    - cluster
      Manages cluster features, gateways, and cluster-wide settings.

      - dump containerinfo
        Returns detailed information about one or more specified containers.
      - dump containers
        Returns information about containers in a cluster.
      - dump replicationmanagerinfo
        Returns information about which containers are under or over replicated in a specified volume.
      - dump replicationmanagerqueueinfo
        Returns information that enables you to identify containers that are under-replicated or over-replicated.
      - dump rereplicationinfo
        Returns information about the ongoing re-replication of replica containers.
      - dump rereplicationmetrics
        Displays information about containers that were copied by the replication manager.
      - dump rolebalancerinfo
        Returns information about active replication role switches.
      - dump rolebalancermetrics
        Returns the cumulative number of times that the replication role balancer has switched the replication role of name containers and data containers on the cluster.
