New 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

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 earlier on this page. Documentation for the customer-managed platform remains on the website you are currently using.

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 Supports Logon Required?
New repository https://package.ezmeral.hpe.com/ All releases Yes
Old repositories https://package.mapr.com/


Release 7.3.0 with EEP 9.1.1 and earlier1 No

1The old repositories will be retired in October 2023 and do not provide access to newer software (releases 7.4.0 and later).

All HPE Ezmeral Data Fabric users are encouraged to begin using the new repository as soon as possible. Newer releases will be available only on the new repository. The old repositories will continue to be available only for a limited time.

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 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 7.4.0 requires EEP 9.1.2 or later. EEP 9.1.2 is new for this release and delivers updates to various ecosystem components but no new components. EEP 9.1.2 can be used with release 7.4.0 or with release 7.3.0.

For more information about new features delivered as part of the Ecosystem Pack, see What's New in EEP 9.1.2. For reference information, see EEP 9.1.2 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 7.4.0 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.

For more information, see Configuring SSO.

Data Access Gateway 6.1 Support

For the gateway to lightweight client applications, release 7.4.0 requires Data Access Gateway 6.1. Data Access Gateway 6.1 can only be used with core 7.4.0, 7.3.0, or 7.2.0 with some restrictions.
CAUTION: Streams users who upgrade from release 7.1.0 (DAG 5.0) or release 7.2.0 (DAG 5.1) to release 7.3.0 (DAG 6.0) or 7.4.0 (DAG 6.1) will not be able to access topics configured using the pre-DAG 6.0 mapping rules.

For more information, see Understanding the HPE Ezmeral Data Fabric Data Access Gateway and the Data Access Gateway 6.1 Release Notes.

JDK 17 Support

As indicated in the Java Support Matrix, release 7.4.0 can be used in JDK 11 or in JDK 17 installations. EEP 9.1.2 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.
