**Indicates a link to the Data Fabric as-a-service documentation.

***HPE Ezmeral Ecosystem Pack (EEP) components do not support IPv6.

No Support for Oracle Enterprise Linux (OEL)

Release 7.7.0 and some earlier core and EEP releases of the HPE Ezmeral Data Fabric support Oracle Enterprise Linux. Release 7.8.0 does not support any version of OEL. For OEL support information, see the Operating System Support Matrix.

Monitoring Packages Moved to Core Repository

Beginning with release 7.8.0 and EEP 9.3.0, the monitoring components are provided in the Data Fabric (core) repository and are not present in the EEP repository. Monitoring packages include the following:

mapr-collectd
mapr-elasticsearch
mapr-fluentd
mapr-grafana
mapr-kibana
mapr-opentsdb

For example, the RHEL monitoring packages for release 7.8.0 can be found at:

https://package.ezmeral.hpe.com/releases/v7.8.0/redhat/

The RHEL monitoring packages are not present in the repository for EEP 9.3.0 at:

https://package.ezmeral.hpe.com/releases/MEP/MEP-9.3.0/redhat/

The same is true for the monitoring packages for Rocky Linux, Ubuntu, SLES, and Oracle Enterprise Linux.

New Repository for NFS v4 on SLES 15

In release 7.8.0, the /releases directory of package.ezmeral.hpe.com includes two suse repositories:

The suse15.5 repository is new and enables support for NFS or NFS v4 for installations on SLES 15 SP3 and SP5. To use the old and new suse repositories, see this table:

Repository	Use this respository to install	NFS Support
`suse`	SLES 15 SP2	NFS
`suse15.5`	SLES 15 SP3 or SP4 or SP5	NFS or NFS v4

New Key for Signature Verification for Data Fabric Files

Release 7.6.1 implemented a new key for .rpm, .tar.gz, .zip, and .tgz files for the following Data Fabric products:

HPE Ezmeral Data Fabric core 7.6.1 and later
HPE Ezmeral Data Fabric clients
HPE Ezmeral Ecosystem Pack (EEP) 9.2.1 and later
Installer 1.18.0.5 and later

Before you install these products, you must import the HPE GPG public keys. This is a one-time operation on each node where packages are installed. Importing the keys allows you to, optionally, verify the GPG and RPM signatures for the products. A verified GPG or RPM signature attests that the product you received has been signed with digital private keys held only by HPE. Successful signature verification also ensures that the file has not been altered after it was signed and released by HPE.

For more information, see HPE GPG Public Keys for GPG or RPM Signature Verification.

Product Name Change: HPE Ezmeral Data Fabric – Customer Managed

With release 7.3.0, the user-managed version of the platform changed its name to HPE Ezmeral Data Fabric – Customer Managed. "HPE Ezmeral Data Fabric" now refers to the as-a-service version of the platform, described later on this page. Documentation for the customer-managed platform remains on the website you are currently using.

SaaS-Based HPE Ezmeral Data Fabric

Release 7.3.0 introduced a new HPE Ezmeral Data Fabric that can be used "as-a-service" and provides consumption-based pricing. Documentation for the new platform has its own website. For more information, see:

HPE Ezmeral Data Fabric Documentation

The new as-a-service HPE Ezmeral Data Fabric leverages the strengths of its predecessor, the HPE Ezmeral Data Fabric – Customer Managed platform. The as-a-service platform improves on its predecessor in many ways. The following table compares the platforms:

Feature	HPE Ezmeral Data Fabric	HPE Ezmeral Data Fabric – Customer Managed
Distributed File System	Yes	Yes
Global Namespace (GNS)	Yes	No
Object Support	Yes	Yes
Table Support	Yes	Yes
Event Stream Support	Yes	Yes
NFSv4 Support*	Yes	Yes
Container Storage Interface (CSI) Support	Yes	Yes
Database Support	Yes	Yes
Client Support	Yes	Yes
Single Sign-On (SSO) Support	Yes	Yes
Platform Management	Managed by HPE	User managed
Billing and Licensing	Consumption-only and some form of term (term-only not supported)	Consumption and Term
Air-Gap Support	Yes	Yes
Graphical User Interface	Data Fabric UI or Control System	Data Fabric UI or Control System
`maprcli` Command Line	Yes	Yes
Scale (number of nodes per fabric / cluster)	See note **	Thousands of nodes
EEP (HPE Ezmeral Ecosystem Pack)	No	Yes
OpenTelemetry (OTel)	Yes	Yes

*NFSv3 is not supported.

**For cloud deployments, the nodes and instances are predetermined based on the storage tier that you select during installation. While new fabrics can be added at any time, adding nodes after fabric creation is not currently supported for cloud deployments. For on-premises deployments, you determine the number of nodes at create time. You can add nodes later by using the steps in Adding Nodes.

New Repository for Data Fabric Software

On August 1, 2023, Hewlett Packard Enterprise introduced a new download repository for the HPE Ezmeral Data Fabric core and ecosystem software packages. https://package.ezmeral.hpe.com/ is the new repository for HPE Ezmeral Data Fabric downloads. For all Data Fabric releases, https://package.ezmeral.hpe.com/ replaces two older repositories:

Description	URL	Authentication Required?
New repository	https://package.ezmeral.hpe.com/	Yes
Old repositories	https://package.mapr.com/ https://package.mapr.hpe.com	Yes¹

¹Beginning October 2023, the old repositories are redirected to the new repository URL, which requires authentication.

The new repository requires you to provide the email and token for your HPE Passport account. Software that points to the old repositories must be updated to include your HPE Passport email and token. For more information about using the new repository, see Using the HPE Ezmeral Token-Authenticated Internet Repository.

If you plan to use the Data Fabric Installer, you must update the Installer to the most current 1.18.0.3 version or later. Earlier versions of the Installer will not work with the new repository. See Updating the Installer.

HPE Ezmeral Ecosystem Pack (EEP) Support

Release 7.8.0 requires EEP 9.3.0 or later. EEP 9.3.0 is new for this release and delivers updates to various ecosystem components but no new components. EEP 9.3.0 can only be used with release 7.8.0.

For more information about new features delivered as part of the Ecosystem Pack, see What's New in EEP 9.3.0. For reference information, see EEP 9.3.0 Reference Information.

For information about the EEPs that can be used with different versions of core releases, see EEP Support and Lifecycle Status.

SSO Support for Keycloak

HPE Ezmeral Data Fabric release 7.8.0 supports SSO when configured with the Keycloak identity and access management (IAM) solution. Other IAM solutions are not currently supported.

Configuring SSO is optional. If you do not configure SSO, you must use Data Fabric user names and passwords for access to the fabric. While SSO is supported for Data Fabric core, it is not currently supported for ecosystem components or the Installer.

Beginning with release 7.5.0, Keycloak is preconfigured and preinstalled if you:

Install the mapr-keycloak package as part of cluster creation
Specify the -keycloak option when you run the configure.sh script

For more information, see Configuring SSO.

Data Access Gateway 6.3.0.1 Support

For the gateway to lightweight client applications, release 7.8.0 requires Data Access Gateway 6.3.0.1. Data Access Gateway 6.3.0.1 can be used with core 7.8.0, 7.7.0, 7.6.1, 7.5.0, 7.4.0, 7.3.0, and 7.2.0 with some restrictions. However, Data Access Gateway 6.3.0.1 is part of EEP 9.3.0, and EEP 9.3.0 is currently supported only for use with core 7.8.0.

CAUTION

Streams users who upgrade from release 7.1.0 (DAG 5.0) or release 7.2.0 (DAG 5.1) to one of the following releases will not be able to access topics configured using the pre-DAG 6.0 mapping rules:

7.8.0 (DAG 6.3.0.1)
7.7.0 (DAG 6.3)
7.6.1 (DAG 6.2)
7.5.0 (DAG 6.2)
7.4.0 (DAG 6.1)
7.3.0 (DAG 6.0)

For more information, see Understanding the HPE Ezmeral Data Fabric Data Access Gateway and the Data Access Gateway 6.3 Release Notes.

JDK 17 Support

As indicated in the Java Support Matrix, release 7.8.0 can be used in JDK 11 or in JDK 17 installations. EEP 9.3.0 can also be used in JDK 11 or JDK 17 installations. However, the Installer is supported only on JDK 11, and if new cluster nodes require a JDK at installation time, the Installer can only install JDK 11.
