This new open source complement to HDFS and Apache HBase is designed to fill gaps in Hadoop’s storage layer that have given rise to stitched-together, hybrid architectures.
The set of data storage and processing technologies that define the Apache Hadoop ecosystem are expansive and ever-improving, covering a very diverse set of customer use cases used in mission-critical enterprise applications. At Cloudera, we’re constantly pushing the boundaries of what’s possible with Hadoop—making it faster,
This new core security layer provides a unified data access path for all Hadoop ecosystem components, while improving performance.
We’re thrilled to announce the beta availability of RecordService, a distributed, scalable, data access service for unified access control and enforcement in Apache Hadoop. RecordService is Apache Licensed open source that we intend to transition to the Apache Software Foundation. In this post, we’ll explain the motivation, system architecture,
Thanks to Holden Karau (@holdenkarau), Software Engineer at Alpine Data Labs (also a Spark contributor and book author), for providing the following post about her work on new base classes for testing Apache Spark programs.
Testing in the world of Apache Spark has often involved a lot of hand-rolled artisanal code, which frankly is a good way to ensure that developers write as few tests as possible. I’ve been doing some work with Spark Testing Base (also available on Spark Packages) to try and make testing Spark jobs as easy as “normal”
Apache Spark continues to be a major theme in the Strata + Hadoop World conference series; here are highlights at NYC next week.
Strata + Hadoop World NYC 2015 (Sept. 29-Oct. 1; if you haven’t registered yet, a 20% discount is still available) is a learning bonanza for many reasons, but this year the focus on Apache Spark and its growing importance in the Apache Hadoop ecosystem is notable.
Recent Impala testing demonstrates its scalability to a large number of concurrent users.
Impala, the open source MPP query engine designed for high-concurrency SQL over Apache Hadoop, has seen tremendous adoption across enterprises in industries such as financial services, telecom, healthcare, retail, gaming, government, and advertising. Impala has unlocked the ability to use business intelligence (BI) applications on Hadoop; these applications support critical business needs such as data discovery,
