8.0.0 Administration
This section describes how to manage the nodes and services that make up a cluster.
- Working with Multiple Fabrics Using the Data Fabric UI
  This section describes how you can get started learning about, installing, and using the HPE Data Fabric.
- 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 Data Fabric clusters.
- Administering Files and Directories
- Administering Tables
  Administration of the HPE Data Fabric Database is done primarily via the command line (maprcli) or with the Managed Control System (MCS). Regardless of whether the HPE 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 Data Fabric Database administration is associated with tables, columns and column families, and table regions.
- Administering Streams
- Administering Data Fabric Gateways
  A HPE Data Fabric gateway mediates one-way communication between a source HPE Data Fabric cluster and a destination cluster. You can replicate HPE Data Fabric Database tables (binary and JSON) and HPE Data Fabric Streams streams. HPE 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 Data Fabric clusters securely.
- Administering the Data Access Gateway
  The HPE 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 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.
  - maprcli and REST API Syntax
    This section provides information about the HPE Data Fabric command API. Most commands can be run on the command-line interface (CLI), or by making REST requests programmatically or in a browser.

    - disksetup
      Describes the disksetup command that formats disks for use by HPE Data Fabric storage.
    - ectool
      Dumps or checks the validity of the stripelets in the backend volume that is associated with the volume configured for warm tiering.

    - guts
      guts is a tool to measure/analyse performance. In the default mode, it prints one line every second, and counts the number of operations or bytes-processed in one second intervals. guts is an internal utility, and is subject to change without notice.
    - manageSSLKeys.sh
      Use the manageSSLKeys.sh utility to create and manage SSL certificates.
    - mapr-support-collect.sh
      Collects information about a cluster's recent activity, to help Data Fabric Support diagnose problems.
    - mapr-support-dump.sh
