7 Reasons Why Java Developers Should Learn Hadoop

Imagine there are two girls standing in front of you – The first girl is cute, beautiful, interesting and has the smile that any guy would die for. And the other girl is average-looking, quiet, not-so-impressive… no different from the ones that you usually see in the restaurant cash counter. Which girl will you call out for a date? If you’re like me, you will choose the attractive girl. You see, life is full of options and making the right choice is what matters the most.
