About Release 8.0.0
This site contains documentation for HPE Data Fabric release 8.0.0, including installation, configuration, administration, and reference content, as well as content for the associated ecosystem components and drivers.
8.0.0 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.
- Planning the Cluster
  Describes information and factors used in planning your cluster.
- Installation Methods
  Describes different ways to install the HPE Data Fabric.
- Installing the HPE Data Fabric File Store
  Describes how to install File Store software with or without the Installer.
- Installing the HPE Data Fabric Object Store
  Describes installation of the HPE Data Fabric Object Store software with or without the Installer.
- Installing Kubernetes Interfaces for Data Fabric
  This section describes how to plan for and install the Container Storage Interface (CSI) Storage Plugin and the Kubernetes Interfaces for Data Fabric FlexVolume Driver.
- Setting Up Clients and Services
  Describes how to set up and use interfaces to an HPE Data Fabric cluster from a client computer.
- Setting Up the Control System
  Describes how to configure and access the Control System.
- Migrating to the HPE Data Fabric
  Provides instructions for migrating business-critical data and applications from an Apache Hadoop cluster to an HPE Data Fabric cluster.
- Applying a Patch
  You can apply a patch by using the Installer, by using the command line (a manual process), or by using an Installer Stanza.
  - Downloading a Patch
    Patches for the HPE Data Fabric can be downloaded from a secure FTP server.
  - Applying a Patch Using the Installer
    The Installer automates much of the work involved in applying patches.
  - Applying a Patch Manually
    HPE Data Fabric patches are version-specific and cumulative. Each patch contains the code fixes that were included in the previous patch for that release version.
  - Applying a Patch Using an Installer Stanza
    Applying a patch using an Installer Stanza leverages the automation provided by the patch-install capability of the web-based Installer.
  - Rolling Back a Patch
    Removing a previously installed patch is a manual process. You can revert to a previous version of the patch by first removing the current patch and then installing the previous version.
  - Applying a Patch for an Ecosystem Component
    Patches for ecosystem components are handled differently from patches for Data Fabric core software.
  - Special Considerations for Control System Patches
    Patches for the Control System are handled differently from patches for cluster data nodes and CLDB nodes.
  - Special Considerations for FUSE POSIX Patches
    Patches for some features, such as the FUSE POSIX client, can require post-installation steps.
  - Applying a Patch to a POSIX Client
    This procedure enables you to apply a patch to any of the HPE Data Fabric POSIX clients, which include the loopbacknfs POSIX client, the FUSE-based POSIX basic client, and the FUSE-based POSIX platinum client.
  - Applying the Patch to Configure Maximum Allowed Concurrent User Sessions
    Describes the procedure to apply the patch to configure the maximum allowed concurrent sessions for Data Fabric users.

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

Special Considerations for FUSE POSIX Patches

Patches for some features, such as the FUSE POSIX client, can require post-installation steps.

When you install a FUSE POSIX patch, a new and backup copy of the fuse.conf file are created in the /opt/mapr/conf directory. These files are called:

fuse.conf.new
fuse.conf.old

You can find the new parameters in the fuse.conf.new file. If needed, you can copy the new parameters to your existing fuse.conf file and restart FUSE for the settings to take effect.

For FUSE POSIX configuration information, see Configuring the HPE Data Fabric FUSE-Based POSIX Client.
