This week's episode of Experts @ Work with Jeremy Zawodny, we sit down with Eric Baldeschwieler, who leads a team of engineers at Yahoo! that has spent the last 18 months enhancing the Hadoop open source project to run on thousands of computers. They have supported a large community of internal users of Hadoop on shared clusters. Eric has lead large scale infrastructure projects to support web search and other activities at Yahoo! and Inktomi since 1996.
