Hi Manoj

1) If you are using VMWare player - then you can have CDH3 and CDH4. When you start the player - you can select which version you want to start.

2) Hadoop 2.0 - will be covered in detail in Module 17 and all the differences and how to migrate will be explained in the class. We will also cover the changes in MapReduce v1.0 and v2.0

Thanks
