We’re pleased to announce the release of Cloudera Enterprise 5.4 (comprising CDH 5.4, Cloudera Manager 5.4, and Cloudera Navigator 2.3).
Cloudera Enterprise 5.4 (Release Notes) reflects critical investments in a production-ready customer experience through governance, security, performance and deployment flexibility in cloud environments. It also includes support for a significant number of updated open standard components–including Apache Spark 1.3, Impala 2.2, and Apache HBase 1.0 (as well as unsupported beta releases of Hive-on-Spark data processing and OpenStack deployments).
Following these best practices can make your upgrade path to CDH 5 relatively free of obstacles.
Upgrading the software that powers mission-critical workloads can be challenging in any circumstance. In the case of CDH, however, Cloudera Manager makes upgrades easy, and the built-in Upgrade Wizard, available with Cloudera Manager 5, further simplifies the upgrade process. The wizard performs service-specific upgrade steps that, previously, you had to run manually, and also features a rolling restart capability that reduces downtime for minor and maintenance version upgrades.
Cloudera Director 1.1 introduces new features and improvements that provide more options for creating and managing cloud deployments of Apache Hadoop. Here are details about how they work.
Cloudera Director, which was released in October of 2014, delivers production-ready, self-service interaction with Apache Hadoop clusters in cloud environments. You can find background information about Cloudera Director’s purpose and fundamental features in our earlier introductory blog post and technical overview blog post.
An improved upgrade wizard in Cloudera Manager 5.3 makes it easy to upgrade CDH on your clusters.
Upgrades can be hard, and any downtime to mission-critical workloads can have a direct impact on revenue. Upgrading the software that powers these workloads can often be an overwhelming and uncertain task that can create unpredictable issues. Apache Hadoop can be especially complex as it consists of dozens of components running across multiple machines.
We’re pleased to announce the release of Cloudera Enterprise 5.3 (comprising CDH 5.3, Cloudera Manager 5.3, and Cloudera Navigator 2.2).
This release continues the drumbeat for security functionality in particular, with HDFS encryption (jointly developed with Intel under Project Rhino) now recommended for production use. This feature alone should justify upgrades for security-minded users (and an improved CDH upgrade wizard makes that process easier).
Here are some of the highlights (incomplete;
