I've been asking my colleague Loraine Lawson a lot of questions lately about what Hadoop is and isn't, trying to better understand it and the skills required. Probably a lot of folks are in the same boat.
She kindly passed along this SearchSOA piece, which says that though Hadoop requires Java skills, Hadoop probably will be a different type of Java development project. It says Big Data analytics shares similarities with traditional SOA and batch-oriented development.
Helena Schwenk, analyst at MWD Advisors, told the site:
Hadoop is "not about real time operational [business intelligence], but more about the discovery, exploration and analysis of large amounts of multistructured data."
She said it calls for more than a single platform or engine, but rather a variety of technologies, components and architectures. Among the skills and experience she mentions:
It's unlikely you'll find all those things in a single person and it's quite likely you'll need to broaden skills on your staff with more training, she says.
