How-to: Build a Prediction Engine using Spark, Kudu, and Impala

Categories: Guest Impala Kudu Spark

Thanks to Richard Williamson of Silicon Valley Data Science for allowing us to republish the following post about his sample application based on Apache Spark, Apache Kudu (incubating), and Apache Impala (incubating).

Why should your infrastructure maintain a linear growth pattern when your business scales up and down during the day based on natural human cycles? There is an obvious need to maintain a steady baseline infrastructure to keep the lights on for your business,

The Barclays Data Science Hackathon: Using Apache Spark and Scala for Rapid Prototyping

Categories: Guest Spark Use Case

In this guest post, members of the Barclays Advanced Data Analytics Team describe the results of an offsite hackathon to develop a recommendation system using Apache Spark.

In the depths of the cold, wet British winter, the Advanced Data Analytics team from Barclays escaped to a villa on Lanzarote, Canary Islands, for a week to collaboratively solve a key business problem: how to design a better customer experience. We framed the problem in the context of using customer shopping behavior data to build a personalized recommender system.

Genome Analysis Toolkit: Now Using Apache Spark for Data Processing

Categories: Data Science Spark Use Case

Users of the latest release of the Genome Analysis Toolkit, an open source framework for analyzing high-throughput DNA sequencing data, can now choose Apache Spark for data processing.

Ever since the Human Genome Project produced the first draft sequence of the human genome in 2000, the cost of sequencing has dropped exponentially, from around US$100 million per genome then to around US$1,000 today. Over the same period, we have seen massive growth in the storage and processing capabilities of big data technologies like Apache Hadoop.

Time Series for Spark Joins Cloudera Labs

Categories: Cloudera Labs Spark

Bringing Time Series for Spark into Cloudera Labs is a reflection of its potentially future usefulness in more use cases.

Time is more important than ever to data. We’re not merely interested in how things are, but how they change, where tendencies lead, and where trends are heading into unusual territory. Many classic machine-learning techniques do nothing in particular with time, and so assume the past and future are all similar.
