HPE Ezmeral Data Fabric 6.2 Documentation

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.
- Planning the Cluster
  Describes information and factors used in planning your cluster.
- Installing Core and Ecosystem Components
  Describes how to install HPE Ezmeral Data Fabric software and ecosystem components with or without the Installer.
- Installing HPE Ezmeral Data Fabric XD Distributed File and Object Store
  Describes how to install XD 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.
- Upgrading Core or MEP Components
  Depending on your current configuration, you may choose to upgrade the release version (core), ecosystem components, clients, or monitoring components.
- Setting Up Clients and Services
  Describes how to set up and use interfaces to a HPE Ezmeral 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 Ezmeral Data Fabric
  Provides instructions for migrating business-critical data and applications from an Apache Hadoop cluster to an HPE Ezmeral 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 Ezmeral Data Platform 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 Ezmeral 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 must be done manually. Alternatively, you can revert to a previous version of the patch by installing over a newer version. To minimize the impact of this change on your cluster, contact MapR Support for technical assistance.
  - Special Considerations for the 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 Ezmeral Data Fabric POSIX clients, which include the loopbacknfs POSIX client, the FUSE-based POSIX basic client, and the FUSE-based POSIX platinum client.

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.
