Describes the new features in release 7.2.0 and provides links to more information.

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 7.2.0 requires EEP 9.1.0 or later. EEP 9.1.0 is new for this release and delivers updates to various ecosystem components but no new components. EEP 9.1.0 can only be used with release 7.2.0.

For more information about new features delivered as part of the Ecosystem Pack, see What's New in EEP 9.1.0. For reference information, see EEP 9.1.0 Reference Information.

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

JDK 17 Support

As indicated in the Java Support Matrix, release 7.2.0 can be used in JDK 11 or in JDK 17 installations. EEP 9.1.0 can also be used in JDK 11 or JDK 17 installations. However, the Installer and Monitoring components are supported only for JDK 11, and if cluster nodes require a JDK, the Installer can only install JDK 11.

Volume Mirroring Prioritization

You can allocate a percentage of the CLDB memory for mirroring by configuring the cldb.memory.mirror.factor parameter in the CLDB config file. For more information about cldb.memory.mirror.factor, see cldb.conf.

Erasure Coding (EC) Enhancements

Release 7.2.0 includes support for the 2+2 erasure coding scheme. For more information, see Erasure Coding Scheme for Data Protection and Recovery.

Hadoop 3 Support

Release 7.2.0 with Ecosystem Pack 9.1.0 includes support for Hadoop 3.3. Hadoop 3.x support enables EEP 9.1.0 to support other updated components, such as Spark 3.3. For more information about Hadoop 3, see the following:
