This document provides a summary of the latest updates in Cloudera Runtime 7.3.2 and its Service Packs and Cumulative Hotfixes. It
includes new features, improvements, known and fixed issues, technical previews, and more.
For detailed, component-level information, see the Cloudera
documentation.
Understanding Cloudera
platform versioning
Starting with
Cloudera 7.3.2.0, versioning follows
the <Base>.<Major>.<Minor>.<Patch> format:
- Base: Indicates the platform base
version.
- Major: Represents the major version.
- Minor: Represents the minor version.
- Patch: Identifies a Cumulative Hotfix (CHF)
or Service Pack (SP). A value of
0 in this position denotes
a standard minor release.
For example, in version
7.3.2.0,
7 is the base version,
3 is the major version,
2 is the minor
version, and
0 indicates that it is an initial minor
release (not a CHF or SP). For more details, see the
Cloudera Platform Support Policy.
Business value and strategic benefits of Cloudera
7.3.2.0
Cloudera 7.3.2.0 delivers three primary business benefits focused on cost efficiency,
risk mitigation, and expanded operational capabilities:
- Significant cost savings and infrastructure
efficiency
- Cloudera 7.3.2.0 release introduces powerful automation and optimization
tools that maximize existing resources and lower operational
expenditures:
-
-
Storage cost reductions: The
new Cloudera Storage Optimizer automatically
identifies infrequently accessed data in Ozone and
converts it to space-efficient erasure coding. This process
reduces the storage footprint by 45% to 60%, effectively
providing additional usable capacity without increasing
licensed capacity.
-
Optimized compute costs:
Hive now supports ARM architecture (such
as AWS Graviton), enabling you to run heavy workloads on
significantly more cost-effective and energy-efficient
hardware.
-
Automated table maintenance:
The Cloudera Lakehouse Optimizer provides automated
table maintenance for Iceberg tables, which
simplifies table management, accelerates query performance,
and directly reduces operational overhead and costs.
- Comprehensive risk reduction and regulatory
compliance
-
Cloudera 7.3.2.0 release improves centralized authorization and
cryptography to address business risks associated with data
governance and security:
-
-
Unified cloud data
governance:
Apache Ranger Remote Authorization Service (RAZ)
now natively supports Amazon S3-compatible object stores.
This enables administrators to apply consistent access
policies to secure sensitive data across diverse cloud
environments.
-
Hardened security baselines:
Cloudera has upgraded core components to JDK 17,
utilizing stronger cryptographic algorithms to
reduce security vulnerabilities and ensuring long-term patch
support.
-
Enhanced FIPS compliance:
Ozone now supports fully FIPS-compliant
SASL mechanisms (DIGEST-SHA), replacing legacy protocols
(such as MD5 and DES) with SHA256 and AES to meet strict
regulatory standards.
- Operational scalability and
future-proofing
-
The update delivers critical networking and high-availability
features that unlock new use cases and ensure the platform scales
with modern business demands:
-
-
Network scalability:
IPv6 dual-stack functionality now spans major
components, including HBase, Hive, Impala, Kafka, Kudu,
Phoenix, Cloudera Data Explorer (Hue), and
ZooKeeper. This ensures seamless communication
over both IPv4 and IPv6 to future-proof deployments.
-
Advanced disaster recovery:
Organizations can now leverage Apache Flink to
replicate Kudu tables across clusters continuously,
capturing only changed rows to support critical disaster
recovery scenarios efficiently.
-
Simplified data modeling:
Support for one-dimensional arrays in Kudu and
Impala allows data teams to store multiple
related values in a single column. This improves query
performance and unlocks new analytics use cases by
eliminating resource-heavy joins.
