Yahoo has been a vociferous Apache Hadoop user and supporter for several years now, and uses it extensively within its Search technologies. Hadoop has been gaining popularity in the Cloud Computing space, with companies like the NYTimes converting 4TB and 11 million articles to PDFs in under 24 hours using Hadoop and EC2 in late 2007. Hadoop has been made available in Amazon's cloud and Yahoo has now released its own Hadoop version.
