I would say go for it. Hadoop is becoming more of a norm in industry and I can tell you from personal experience that having prior hands-on Hadoop work makes your resume pop a little more.

Even better is if you're able to muck around in core Hadoop versus abstracted management layers like Cloudera. The things you have to learn in maintaining a Hadoop cluster like cloud systems management, tuning, running jobs, etc. makes for valuable experience, even if niche.
