So here it is.

I am getting many times questions like how much it takes to learn Hadoop? How much time I need to spend on training before I can start my professional career in that area.

The short answer I have: “No free Lunch”.
I might be old school but I honestly believe that in order to be great in something, you must have the passion.

My short answer is: 3-5 months.

Assumptions:

• You have great Java programming background (Hadoop was written in JAVA) – I heard about guys who knew only JAVASCRIPT and perl,…
• You dont just read but you actually setup your own cluster with 2-3 nodes and code – yes code.
• You get 2-3 books, read and practice.

Next time I will elaborate on my short answer.

Cheers,
