It is time for your kids to start learning about Hadoop, the formless data repository that is the current favorite of many dot-coms and the darling of the data nerds. Indeed, the younger the better. The Hadoop ecosystem is a big tent and getting bigger.
To grok it, you have to cast aside several long-held tech assumptions. First, that you know what you are looking for when you build your databases: Hadoop encourages pack rats to store every log entry, every Tweet, every Web transaction, and other Internet flotsam and jetsam. The hope is that one day some user will come with a question that can’t be answered in any way other than to comb through this morass. Who needs to spend months on requirements documents and data dictionaries when we can just shovel our data into a hard drive somewhere? Turns out, a lot of folks.
