Today’s Hadoop World talk comes from Eric Baldeschwieler, Yahoo!’s VP of Hadoop Development. In this talk, Eric highlights Yahoo’s contributions to development and testing of Hadoop at scale, and goes into detail about how Yahoo! uses Hadoop to deliver several popular services. A major thanks to Eric, and everyone else at Yahoo! for their ongoing contributions to, and investment in, Apache Hadoop – it’s hard to imagine where the project would be today without such dedication.
