Cloudera Enterprise 5.8 is Now Available

Categories: CDH Cloudera Manager Hadoop

Cloudera Enterprise 5.8 is now generally available (comprising CDH 5.8, Cloudera Manager 5.8, and Cloudera Navigator 2.7). 

Cloudera is excited to announce the general availability of Cloudera Enterprise 5.8! Main highlights of this release include Impala read/write support on Amazon S3, a redesigned SQL query editor GUI, the expansion of role-based access control functionality to Cloudera Search, and the GA of Cloudera Navigator Optimizer to facilitate and optimize workload migrations.

For those new to it, Cloudera Navigator Optimizer (previously in beta) is a cloud-based service that helps with offload planning and active data optimization for Apache Hadoop. For example, it provides workload visibility and assessments for building a predictable offload plan, adapting to evolving Hadoop data and workload demands, and optimizing query performance in Impala and Apache Hive. (For more details about Cloudera Navigator Optimizer, check out the release blog post.)

As usual, Cloudera Enterprise 5.8 contains a long list of quality enhancements and bug fixes (learn more about our multi-dimensional hardening/QA process) and other improvements across the stack. Here is a partial list of those improvements (see the Release Notes for a full list):
