What's New in Release 6.2.0
Release 6.2.0 of the HPE Ezmeral Data Fabric provides substantial new features for the components of the data platform. This page describes and provides links to more information about the new features.
For new features delivered as part of the Ezmeral Ecosystem Pack, see What's New in EEP 7.1.0.
New Repository for Data Fabric Software
Description | URL | Authentication Required? |
---|---|---|
New repository | https://package.ezmeral.hpe.com/ | Yes |
Old repositories | https://package.mapr.com/ | Yes1 |
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 version 1.18.0.3 or later. Earlier versions of the Installer will not work with the new repository. See Updating the Installer.
Security and Governance Enhancements
- Policy-Based Security
- HPE Ezmeral Data Fabric supplies robust security. In release 6.2, you can leverage the new Policy-Based Security features to apply platform-level security across all data.
- External KMIP Keystore
- Release 6.2 supports external keystores, through KMIP (Key Management Interoperability Protocol), to securely manage the CLDB and DARE master keys at the core platform layer. Release 6.2 supports KMIP versions 1.0 to 1.4 and has been tested with the Utimaco ESKM, Gemalto SafeNet KeySecure, and Vormetric DSM key management servers.
- SSL Encryption for Server-to-Server Communication
- In release 6.2.0, the ZooKeeper version is updated to 3.5.6. Version 3.5.6 supports SSL encryption for server-to-server communication. When you install a new release 6.2 secure cluster, SSL between ZooKeeper servers is enabled automatically. For more information, see configure.sh.
- Resolved Security Vulnerabilities
- For a list of vulnerabilities resolved in this release, see Resolved Issues.
Performance Fixes
- MFS-11674
- Added a
-D|--crc
option to gfsck to enable CRC to be verified without blocking operations on the frontend volume. - MFS-11809
- Added a configuration parameter (cldb.tier.gw.balance.num.vols.per.batch) to set the number of volumes to balance at a time, rather than a default of 5 volumes.
- MFS-11835
- Fixed hangs in POSIX client when connections timeout after being inactive. Added a
parameter
fs.mapr.binding.inactive.threshold
to configure timeout for inactive connections.
Operating System Support
- CORE-623
- HPE Ezmeral Data Fabric supports SLES 15. For a complete list of supported operating systems, see Operating System Support Matrix.
New Products and Features
- Data Tiering Enhancements
- Data tiering was introduced in release 6.1. With release 6.2, you have access to enhanced data-tiering functionality, including Storage Labels, Erasure Coding with Local Parity, and parallel offload with the MAST gateway.
- Ease of Data Management
- Two new features support unlimited scale: Snapshot Restore and Last Access Time.
- Hadoop and YARN Delivered with Ecosystem Components
- Beginning with core 6.2.0 and EEP 7.0.0,
Hadoop and YARN services are no longer included in the HPE Ezmeral Data Fabric repository for core packages. They are provided as
ecosystem components in the MEP(EEP)
repository. This enables Hadoop and YARN to be upgraded separately from the HPE Ezmeral Data Fabric. To decouple Hadoop and YARN from core, the
mapr-mapreduce2
package was removed, and some new packages were added. For more information, see Installing Hadoop and YARN.
- Java / JDK 11 Support
- Release 6.2 and the HPE Ezmeral Data Fabric ecosystem components take advantage of the new features and long-term support provided by JDK 11. For more information, see the JDK Support Matrix.
- Controlling Metrics for JMX-Enabled Services
- Release 6.2 enables you to control how metrics are collected from JMX-enabled services. For more information, see Controlling Access to JMX Metrics.
- Monitoring
- The Control System has been modified for Kubernetes environments. You will notice these modifications if you use the Control System with the HPE Ezmeral Container Platform. To learn more about the HPE Ezmeral Container Platform, see the 5.2 documentation.
- NFSv4 Updated
- Release 6.2 updates the NFSv4 package (
mapr-nfsganesha
) to version 3.3. - N+N EC Scheme Support
- Release 6.2.x supports the N+N EC schemes.
Deprecated Products and Features
- MapR Data Science Refinery
- The MapR Data Science Refinery is not supported in Releases 6.2.0 and later, but continues to be supported in Releases 6.0.x and 6.1.0. For more information about data science tools and applications, see HPE Ezmeral ML Ops.
- Metering Support Removed
- Metering is not supported and the documentation for metering has been removed. The Metering feature was added to support consumption-based billing. Monitoring and metrics capabilities continue to be supported.
Documentation Enhancements
- Quickly Navigate to the Same Topic in a Different Release
- Most documentation pages now include buttons to enable navigation to the same topic in a different release. These buttons appear in the upper right corner of the page:
- New Component Versions Matrix
- A new matrix has been added to the list of Interoperability Matrices. The Component Versions for Released EEPs matrix lets you compare the versions of ecosystem and Monitoring components across different EEPs.
- Revised Product Naming
- Release 6.2 introduces a new name for the data platform:
