September 25, 2012, 1:27 PM — Big data is creating big demand for Apache Hadoop, the open source framework that's known for its ability to store, process and analyze huge amounts of data using commodity servers. With Hadoop, enterprises are able to collect more data, retain it longer and perform analyses that weren't practical in the past because of cost, complexity and a lack of tools.
It's an appealing platform, but it requires expertise. As enterprises weigh the potential for Hadoop in their data architecture plans, IT pros are scrambling to sharpen their skills. Hadoop training courses and certification programs are available from companies including Cloudera, Hortonworks, IBM and MapR. But if you're not ready to commit to formal, paid training courses, there are also free resources that can get a newcomer started on Hadoop or broaden a veteran's skills.
