[ANNOUNCE] Cloudera Enterprise 5.7

Master Collaborator

Cloudera Enterprise 5.7 is now generally available (comprising CDH 5.7, Cloudera Manager 5.7, and Cloudera Navigator 2.6).


Cloudera is excited to announce the general availability of Cloudera Enterprise 5.7! Main highlights of this release include production-ready Hive-on-Spark functionality, which will help users accelerate their use of Apache Spark as a data processing standard; 2x performance gains for Apache Impala (incubating); easier cluster configuration and utilization reporting; and end-to-end encryption for Apache Spark data.


The release also contains a long list of incremental improvements across the stack, in addition to the usual hundreds of bug fixes (some of which were uncovered during our multi-dimensional hardening/QA process). Here is a partial list of those improvements (see the Release Notes for a full list):
