About Release 7.9.0
This site contains documentation for HPE Ezmeral Data Fabric release 7.9.0, including installation, configuration, administration, and reference content, as well as content for the associated ecosystem components and drivers.
7.9.0 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 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.
  - Upgrade Workflows (Releases 6.x or 7.x to 7.9.0)
    This section describes three common methods for upgrading from one core release to another. The workflows in this section introduce you to the high-level steps for each method and provide links to pages showing more detail.
  - Upgrading Data Fabric Software
    This section describes the process of upgrading core, the ecosystem components, and the Data Fabric clients.
  - Upgrading Ecosystem Packs
    Describes how to upgrade Ecosystem Packs (EEPs), either as part of a core upgrade or to take advantage of a new EEP for the current version of core.
    - Planning Ecosystem Pack (EEP) Upgrades
      The set of ecosystem components that you run in the cluster must all belong to the same EEP.
    - Preparing to Upgrade the Ecosystem Pack
      Complete these pre-upgrade steps for each ecosystem component in the EEP that you want to upgrade.
    - Upgrading the Ecosystem Pack With the Installer
      If the cluster that you want to upgrade was installed using the Installer, you can use the Installer to upgrade the Ecosystem Pack (EEP).
    - Upgrading the Ecosystem Pack Without the Installer
      After you upgrade core without using the Installer, you need to upgrade ecosystem components with manual steps. First, verify that your repository is configured to use an Ecosystem Pack (EEP) that is supported by your cluster version. Then, upgrade each component manually.
    - Finishing the Ecosystem Pack Upgrade
      Complete the post-upgrade steps for each ecosystem component that was upgraded.
  - Preparing the Cluster for a Maintenance Update
    This section identifies how to prepare for applying either a minor update or a patch.
  - Performing a Maintenance Update
    Perform a maintenance update when you want to upgrade to a new patch version of core or apply a patch.
- 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.
- 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.
7.9.0 Data Fabric
HPE Ezmeral Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
7.9.0 Administration
This section describes how to manage the nodes and services that make up a cluster.
7.9.0 Development
This section contains information related to application development for Ezmeral ecosystem components and HPE Ezmeral Data Fabric products, including the file system, Database (Key-Value and JSON), and Event Streams.
Other Docs
This section contains release-independent information, including: Installer documentation, Ecosystem release notes, interoperability matrices, security vulnerabilities, and links to other data-fabric version documentation.

Upgrading the Ecosystem Pack With the Installer

If the cluster that you want to upgrade was installed using the Installer, you can use the Installer to upgrade the Ecosystem Pack (EEP).

About this task

Procedure

Verify that all ecosystem components are prepared for an upgrade.

WARNING
Service failures, job failures, or the loss of customized configuration files can occur if you do not perform the steps to prepare ecosystem components for an upgrade.
Update the Installer. For more information, see Updating the Installer.
This step ensures that the Installer has access to the latest packages.
Halt jobs and applications. Stop accepting new jobs and applications, and stop YARN applications.
```
# yarn application -list
# yarn application -kill <ApplicationId>
```
You might also need specific commands to terminate custom applications.
Launch the Installer URL ( https://<hostname/IPaddress>:9443).
Select the Incremental Install option.
Select the EEP Version to which you want to upgrade, and complete the upgrade through the Installer.
Once the upgrade through the Installer is complete, perform the post-upgrade steps. See Finishing the Ecosystem Pack Upgrade.
