About

I am a graduate student majoring computer science, in Seoul National University, Korea. My major interest is big data analysis using MapReduce. I write code mainly with Java.

In this blog, I will write some tutorials related to Hadoop, and introduce some 5-minutes quick tutorials of useful Java libraries.

Although my original name is Dongjin, all my friends and colleagues outside of Korea call me Tommy. It was originated from my baptismal name, Thomas Aquinas.
