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):   Performance & Scale Impala queries now 3x faster on Kerberized clusters Significant performance improvements to Hive metadata replication in BDR Usability & Management Streamlined offload planning and active data optimization with Cloudera Navigator Optimizer Redesigned SQL editor in Hue Hive jobs can now be assigned to specific YARN resource pools based on Sentry policy (instead of default “hive” pool) Native Cloud Support Apache Sentry support for Amazon S3 Impala can now read and write to Amazon S3 Security & Governance Role-based access control (Sentry) support for Impala and Hive queries over Amazon S3 Sentry support for Cloudera Search New policy support for managed metadata assignment Navigator SDK support for Navigator Optimizer integration New or Updated Open Source Components Impala 2.6 Hue 3.10 New or Updated Platform Support Debian 8.2 Oracle JDK 1.8u74 and 1.8u91 Over the next few weeks, we’ll publish blog posts that cover some of these features in detail.
