Hadoop is building a good momentum...
EMC announced enterprise and community distribution as well as appliance of Apache Hadoop. This would be in competition with Cloudera which has a very good traction in Hadoop market. Moreover, Yahoo which has been pioneer in original contribution of Hadoop and a heavy user, is rumoured to be launching Hadoop spin-off. It has contributed Pig as a layer above Hadoop.
During the conference other products like Brisk,which makes Hadoop with Cassendra as a node, and SnapReduce from SnapLogic were also announced. Overall all of these are good indication of Hadoop traction. A more detailed note is in my other blog which is dedicated to emerging technologies and apps.
