6.2 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.
6.2 Data Fabric
HPE Ezmeral Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
6.2 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
  - Managing Schedules
    - Viewing the List of Schedules
      Explains how to view all the schedules using the Control System or the CLI.
    - Creating a Schedule
      Explains how to create a schedule using the Control System or the CLI.
    - Modifying a Schedule
      Explains how to modify a schedule using either the Control System or the CLI.
    - Selecting an Existing Schedule to Associate with a Volume
      Explains how to associate an existing schedule with a volume using the Control System, the CLI, or the REST API.
    - Removing one or more Schedules
      Describes how to remove schedules not associated with any volumes using either the Control System or the CLI.
  - 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

Definitions for commonly used terms in MapR Converged Data Platform environments.

Selecting an Existing Schedule to Associate with a Volume

Explains how to associate an existing schedule with a volume using the Control System, the CLI, or the REST API.

Selecting an Existing Schedule Using the Control System

Procedure

Log in to the Control System and go to Summary tab in the volume details page.
Click the (associated with the type of schedule in the Schedules pane) to display the Edit Schedules window.
Review the name and detail of each schedule and select a schedule from the list.
Click Save Changes to associate the schedule with the volume.

Selecting an Existing Schedule Using the CLI and REST API

About this task

You can associate a schedule with a volume using the schedule parameter when creating or editing a volume. For example:

maprcli volume create -name <volName> -path <mountPath> -schedule <scheduleID>

maprcli volume modify -name <volName> -schedule <scheduleID>

You can associate a schedule with a volume using the schedule parameter when creating or editing a volume. Send a request of type POST. For example:

curl -k -X POST 'https://<hostname>:8443/rest/volume/create?name=<volName>&path=<volPath>&schedule=<scheduleID>' --user mapr:mapr

curl -k -X POST 'https://<hostname>:8443/rest/volume/modify?name=<volName>&schedule=<scheduleID>' --user mapr:mapr
