Cloudera is proud to announce the beta availability of Cloudera Enterprise 6. The new release includes a large number of important upgrades to our open source core components as well as improvements to our unique innovations. We believe Cloudera Enterprise 6 will make your experience more productive and efficient. Please read on to learn about the new features that make Cloudera Enterprise 6 a must-have release. Customer BenefitsGain better insights from structured and unstructured data with Solr 7 integrated search. The vast majority of the data being created is unstructured and tapping that data has been cumbersome. Furthermore, fitting that data into the existing structured data paradigm has required a normalization process that is time-consuming. Solr 7 provides both a deeper level of analysis and opens up the unstructured data universe to traditional BI tools through a SQL interface. For Cloudera Enterprise 6.0 we support the new JSON Facet Module and Nested Documents, while

 Dear CDH, Cloudera Manager, and Cloudera Navigator users, On April 11, 2018, we announced the release of Cloudera Enterprise 5.14.2. Shortly after, we discovered a serious bug in Cloudera Manager 5.14.2.

Please upgrade to this release instead of Cloudera Manager 5.14.2.

Summary: Due to a kernel security exploit on system CPUs (Spectre and Meltdown), OS updates are required for all systems. The OS updates have performance implications. Cloudera is in the process of testing the impact across various Cloudera software services and workloads. Initial test results, based on the limited testing (a subset of services and workloads) we have completed as of January 12, indicate that the performance impact on Cloudera software is minor.   Users affected: While we are not aware of customers who have been impacted by these CPU vulnerabilities, we understand and expect that all Cloudera customers will apply Spectre and Meltdown patches as they become available from their OS suppliers. As such, Cloudera is performing basic functional testing to ensure that CDH works with the patches as well as determining performance impact on typical workloads.   Impact: Cloudera’s initial testing has focused on a subset of commonly used CDH serv
