We’re pleased to announce the release of Cloudera Enterprise 5.3 (comprising CDH 5.3, Cloudera Manager 5.3, and Cloudera Navigator 2.2).
This release continues the drumbeat for security functionality in particular, with HDFS encryption (jointly developed with Intel under Project Rhino) now recommended for production use. This feature alone should justify upgrades for security-minded users (and an improved CDH upgrade wizard makes that process easier).
Here are some of the highlights (incomplete;
A significant vulnerability affecting the entire Apache Hadoop ecosystem has now been patched. What was involved?
By now, you may have heard about the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack on TLS (Transport Layer Security). This attack combines a cryptographic flaw in the obsolete SSLv3 protocol with the ability of an attacker to downgrade TLS connections to use that protocol. The result is that an active attacker on the same network as the victim can potentially decrypt parts of an otherwise encrypted channel.
Installing CDH on newer unsupported operating systems (such as Ubuntu 13.04 and later) can lead to conflicts. These guidelines will help you avoid them.
Some of the more recently released operating systems that bundle portions of the Apache Hadoop stack in their respective distro repositories can conflict with software from Cloudera repositories. Consequently, when you set up CDH for installation on such an OS, you may end up picking up packages with the same name from the OS’s distribution instead of Cloudera’s distribution.
With Cloudera Director, cloud deployments of Apache Hadoop are now as enterprise-ready as on-premise ones. Here’s the technology behind it.
As part of the recent Cloudera Enterprise 5.2 release, we unveiled Cloudera Director, a new product that delivers enterprise-class, self-service interaction with Hadoop clusters in cloud environments. (Cloudera Director is free to download and use, but commercial support requires a Cloudera Enterprise subscription.) It provides a centralized administrative view for cloud deployments and lets end users provision and scale clusters themselves using automated,
Cloudera Enterprise’s newest release contains important new security and performance features, and offers support for the latest innovations in the open source platform.
We’re pleased to announce the release of Cloudera Enterprise 5.1 (comprising CDH 5.1, Cloudera Manager 5.1, and Cloudera Navigator 2.0).
