For more information, see clustergroup addexternal. To import HPE Alletra MP X10000 from the Data Fabric UI, see Importing an external S3 server.

Enhancement to Insights

You can access the insight dashboards by using the Zeppelin UI. For more information, see Configuring Data Fabric to Track User Behavior.

Librdkafka Updated to Version 2.6.0

Beginning with release 7.10.0 and EEP 9.4.0, librdkafka is now updated to version 2.6.0.

IMPORTANT
*Librdkafka 2.6.0 in core 7.10 is not compatible with HPE Ezmeral Data Fabric Stream clients for HPE Ezmeral Data Fabric Streams C#/.NET Applications. Nodes running C# applications should not be upgraded to HPE Ezmeral Data Fabric 7.10.

The Data Fabric 7.10 release supports C API Librdkafka 2.6.0 for HPE Ezmeral Data Fabric Streams. See the following topics for details:

Important Features Introduced in the Previous 7.x Releases

The major features introduced in the earlier Data Fabric releases are listed below for your reference.

IPv6 Support

HPE Ezmeral Data Fabric release 7.6.0 introduced support for IPv6 addresses and support for clusters that have a mix of IPv6 and IPv4 addresses. A new option in the configure.sh script enables the configuration of IPv6 support. For more information, see IPv6 Support in Data Fabric and configure.sh.

Iceberg Support

Release 7.6.0 introduced support for the Iceberg table format. You can use Apache Spark to query Iceberg tables stored in the Data Fabric and perform other operations to take advantage of Iceberg features. For more information, see Iceberg Support and Getting Started with Iceberg.

Support for Third-Party Storage Solutions

With release 7.6.0, the HPE Ezmeral Data Fabric offers global namespace support for NFS- and S3-protocol operations performed against WEKA, VAST Data, Scality, and other third-party, object-storage solutions.

For more information, see Third-Party Storage Solutions. External S3 Support

Release 7.6.0 introduced support for mounting an external NFS server or an external S3 server (including third-party storage solutions) into a cluster group or global namespace. For more information, see clustergroup addexternal.

Assigning Multiple Security Policies to a Volume

Release 7.6.0 introduced support for attaching multiple security policies to one, or more than one, volume in a cluster. For more information, see policy attach.

Support for Third-Party Storage Solutions

With release 7.6.0, the HPE Ezmeral Data Fabric offers global namespace support for NFS- and S3-protocol operations performed against WEKA, VAST Data, Scality, and other third-party, object-storage solutions.

For more information, see Third-Party Storage Solutions.
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.
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.
