I need to evaluate the performance of Amazon MapReduce by executing the terasort program on top of it. But I have no idea how to start the process of evaluation. Could you please help me out by answering the following questions:

 1. How should I write the terasort program (which programming language is suitable for the implementation and for running it in Amazon MR)? Or, is there any existing programs which I can use for my evaluation purpose?
 2. How to use Amazon MapReduce? After creating instances of Amazon EC2, what should I do to use the Amazon MR?

Please dont hesitate to suggest me any readings, if you think that could help me out for this problem. Thanks a lot in advance in anticipation of some early replies.
