Well, you didn't say what your background was or how much experience with Hadoop you currently have from an administrator's perspective. Assuming you are a beginner, I'd recommend reading over a book like this one: • Murthy, A., Vavilapalli, V., Eadline, D., Niemiec, J., & Markham J. (2014).

Upper Saddle River, NJ: Addison-Wesley Professional …to get the relevant introductory information before you start in on your project.
