Yahoo Dev Blog
Today we kicked off the fourth annual Hadoop Summit at the Santa Clara Convention Center, bringing together some of the most influential thought leaders in the space, including Yahoo!, Facebook and IBM, to collaborate on Big Data issues and share experiences in building, managing and operating relevant real-world applications on Hadoop.
Yesterday, together with Benchmark Capital we announced the formation of Hortonworks. This new independent company was founded based on the Hadoop technology pioneered at Yahoo! and will be led by key architects and core contributors to the open source Apache Hadoop technology.
