Re: issue about hadoop hardware choose
Hello Ch Huang,
Do you know this book?
"Hadoop Operations" http://shop.oreilly.com/product/0636920025085.do

I think, it answers most of the questions in detail.

For a production cluster you should consider MRv1.
And I suggest you, to go with more hard drives per slave node to have a
IO bandwith for map reduce, give it 4 x 2 TB at least or even 6.
At least three zookeeper servers are used.

Best wishes
