Hi CDH, Cloudera Manager, and Cloudera Navigator users,
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).
Recently Cloudera made the upgrade process considerably easier via an improved CDH upgrade wizard; see details about that wizard here and best practices here. (Note: Due to metadata format changes in Apache Hadoop 2.6, upgrading to CDH 5.4 and later from any earlier release requires an HDFS metadata upgrade, as well. Note also that for parcel-based installs of CDH 5.4, Cloudera Manager 5.4 is required.)
Over the next few weeks, we’ll publish blog posts that cover some of these features in detail. In the meantime:
