In this installment of our series about how quality assurance is done at Cloudera, learn about the important role of fault injection in the overall process.
Apache Hadoop is the consummate example of a scalable distributed system (SDS); such systems are designed to provide 24/7 services reliably and to scale elastically with the addition of industry-standard hardware cost-effectively. They must be resilient and fault-tolerant to various environmental anomalies.
As you would expect,
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; 4x performance gains for Apache Impala (incubating); easier cluster configuration and utilization reporting; and end-to-end encryption for Apache Spark data.
In this post, engineers from Wargaming.net, the online game developer and publisher, describe the design of their real-time recommendation engine built on CDH.
The scope of activities at Wargaming.net extends far beyond the development of games. We work on dozens of internal projects simultaneously, and our Data-driven Real-time Rules Engine (DDRRE) is among the most ambitious.
DDRRE is a system that analyzes large amounts of data in real time,
The Cloudera Developer Program is kind of amazing. Here’s why.
For those with a desire to build new applications on Cloudera’s platform, historically there’s been a gap to cross between pure bootstrapping on CDH (whether via a small on-premise cluster, in the public cloud, or using Cloudera Live) and obtaining full-blown support for a complete enterprise data hub with all the fixings (including Cloudera Navigator). For individuals who have moved beyond self-learning and are getting “serious,”
The recently-released Apache Hive 2.0 contains some exciting improvements, many of which are already available in CDH 5.x.
Recently, the Apache Hive community announced Hive 2.0.0. This is a larger release compared to the previous one (covered here), with a lengthy list of new features (many experimental), enhancements, and bug fixes. Cloudera’s Hive team have been working with the community for months to drive toward this significant release.
