About Release 7.0
This site contains documentation for HPE Ezmeral Data Fabric release 7.0, including installation, configuration, administration, and reference content, as well as content for the associated ecosystem components and drivers.
7.0 Installation
This section contains information about installing and upgrading HPE Ezmeral Data Fabric software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a HPE Ezmeral Data Fabric cluster.
7.0 Data Fabric
HPE Ezmeral Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
7.0 Administration
This section describes how to manage the nodes and services that make up a cluster.
- Administering Users and Clusters
  Lists topics that help manage a data-fabric cluster.
- Administering Nodes
  Provides a synopsis of managing nodes in a cluster.
- Administering Volumes
  This section provide information about how to organize and manage data using volumes, a unique feature of HPE Ezmeral Data Fabric clusters.
  - Managing Data with Volumes
    Provides an overview of how to manage volume data.
  - Managing Snapshots
    This section provide information about managing snapshots.
  - Managing User Disk Usage
    - Viewing User Disk Usage Information
      Explains how to view user disk usage information using either the Control System or the CLI.
    - Set or Modify Quotas for Users and/or Groups
      Explains how to set or modify quotas for one or more entities using either the Control System or the CLI.
  - Managing Schedules
  - Managing Tiers
  - Managing Storage Policies
  - Using Storage Labels
    Describes the Storage Labels feature.
- Administering Files and Directories
- Administering Tables
  Administration of the HPE Ezmeral Data Fabric Database is done primarily via the command line (maprcli) or with the Managed 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.
- Administering Streams
- Administering Data Fabric Gateways
  A HPE Ezmeral Data Fabric gateway mediates one-way communication between a source HPE Ezmeral Data Fabric cluster and a destination cluster. You can replicate HPE Ezmeral Data Fabric Database tables (binary and JSON) and HPE Ezmeral Data Fabric Streams streams. HPE Ezmeral Data Fabric gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.
- Administering Services
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring Security
  Describes how to configure security and manage secure clusters.
- Managing Secure Clusters
  Provides procedures that will enable you to use MapR clusters securely.
- Administering the Data Access Gateway
  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.
- Planning for High Availability
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
- Troubleshooting Cluster Administration
  Lists the common errors and their solutions.
- Best Practices for Backing Up HPE Ezmeral Data Fabric Information
  Lists the best practices and performance considerations to follow when backing up HPE Ezmeral Data Fabric information.
7.0 Development
This section contains information related to application development for Ezmeral ecosystem components and HPE Ezmeral Data Fabric products, including the file system, Database (Key-Value and JSON), and Event Streams.
Other Docs
This section contains release-independent information, including: Installer documentation, Ecosystem release notes, interoperability matrices, security vulnerabilities, and links to other data-fabric version documentation.

Viewing User Disk Usage Information

Explains how to view user disk usage information using either the Control System or the CLI.

Viewing User Disk Usage Information Using the Control System

About this task

To view information about disk usage by cluster users:

Procedure

Log in to the Control System and go to the User Disk Usage tab under Data > Volumes.

NOTE The Volumes page is under the Volumes menu in the Kubernetes version of the Control System.

The disk usage information for all the users displays. For each user, the Accountable Entities pane displays the following:

Column Name	Column Description
Type	The type of accountable entity (AE). Value can be User or Group.
Accountable Entity	The user or group responsible for the volume.
Disk Usage	The total disk space used by the user.
Volume Count	The number of volumes.
Hard Quota	The user's hard quota.
Advisory Quota	The user's advisory quota.
Email	The email address of the user.

Selecting the checkbox beside an accountable entity makes the Edit Properties button available. You can modify the quotas for the selected entities by clicking Edit Properties. Alternatively, you can click on an entity or associated

to modify the email address and quotas for the entity.

Viewing User Disk Usage Information Using the CLI or REST API

About this task

The basic command to view user disk usage information is:

maprcli entity info -name <entity name> -type <type>
