- Installing the HPE Ezmeral Data Fabric File Store
  Describes how to install File Store software with or without the Installer.
- Installing HPE Ezmeral Data Fabric Object Store
  Describes installation of the HPE Ezmeral 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.
- Upgrading Core or EEP 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 an 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.
  - Planning and Initial Deployment
    There are a number of considerations to take into account before migrating from Apache Hadoop to Data Fabric Hadoop.
  - Component Migration
    This section describes how to migrate customized components to Hadoop for the HPE Ezmeral Data Fabric.
  - Application Migration
    Before you migrate your applications to the Data Fabric Hadoop distribution, consider testing your applications using a small subset of data.
  - Data Migration
    After you migrate your applications to the Data Fabric cluster, you can copy your data from the Apache Hadoop HDFS to the Data Fabric cluster.
  - Node Migration
    You can add decommissioned HDFS data nodes to your 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.

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

Node Migration

You can add decommissioned HDFS data nodes to your HPE Ezmeral Data Fabric cluster.

Once you have loaded your data and tested and tuned your applications, you can add decommission HDFS data-nodes and add them to the Data Fabric cluster.

This is a three-step process:

Decommissioning nodes on an Apache Hadoop cluster: The Hadoop decommission feature enables you to gracefully remove a set of existing data-nodes from a cluster while it is running, without data loss. For more information, see the Hadoop Wiki FAQ.
Meeting minimum hardware and software requirements: Ensure that every data-node you want to add to the Data Fabric cluster meets the hardware, software, and configuration requirements.
Adding Nodes to a Data Fabric cluster: You can add those data-nodes to the Data Fabric cluster. For more information, see Adding Nodes to a Cluster.
