I have a programming background, and I've done lots of database design and written lots of queries with Sql Server.

I am really excited about looking at bigdata solutions. I know almost nothing about it. The way I want to learn is to sign up for a sandbox where I can try things out.

questions

Is there a sandbox where I can play around with hadoop? It does not have to be free. Would amazon EMR be the right path to go?
What technologies should I be looking at to get started quickly?
Is there a 'bigdata' dataset that is available to play with?

Thank you so much for your guidance.
