About Release 8.2.0
This site contains documentation for HPE Data Fabric release 8.2.0, including installation, configuration, administration, and reference content, as well as content for the associated ecosystem components and drivers.
8.2.0 Installation
This section contains information about installing HPE 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.
8.2.0 Upgrade
This section describes how to upgrade HPE Data Fabric software.
8.2.0 Data Fabric
HPE Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
8.2.0 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.
- Troubleshooting Cluster Administration
  Lists the common errors and their solutions.
- Best Practices for Backing Up HPE Data Fabric Information
  Lists the best practices and performance considerations to follow when backing up HPE Data Fabric information.
- IPv6 Support in Data Fabric
  Describes the IPv6 support feature for Data Fabric.
- Moving Objects Across Fabrics and from AWS S3 to Fabric
  Describes how objects are moved or transferred across buckets from one fabric to another or from Amazon S3 to Data Fabric.
  - Object Copier Hub
    Event-based object copier supporting data transfer and deletion between any S3-compatible sources and destinations.
  - Installing the mapr-och package
    Describes how to install the mapr-och package.
  - Prerequisites to use Object Copier Hub to move data from Fabric to Fabric
    Lists the prerequisite settings to use the Object Copier Hub service to move data from a bucket in one fabric to a bucket in another fabric.
  - Prerequisites to use Object Copier Hub to move data from AWS S3 to Fabric
    Lists the prerequisite settings to use the Object Copier Hub service to move objects from a bucket on AWS S3 to a bucket on another fabric.
  - Object Copier Lifecycle
    Describes the object copier lifecycle and the commands associated with the lifecycle.
    - Troubleshooting Object Copier Hub (OCH)
      Troubleshooting tips for Object Copier Hub
    - Sample OCH configuration in JSON format
      Contains a sample OCH JSON format configuration.
    - Replication Rules JSON Format

    - Stopping Copier
      Describes how to stop a copier by using the maprcli and REST.
    - Adding Source and Destination Buckets to Copier
      Describes how to add source and destination buckets to copier by using the maprcli and REST.
    - Removing Source and Destination Buckets for Copier
      Describes how to remove source and destination buckets to copier by using the maprcli and REST.
    - Updating Copier
      Describes how to update copier configuration by using the maprcli and REST.
    - Moving Copier from Current Node to Another Node
