I don't have specific experience upgrading from 1.x to 2.x but I do have to say that if you have Pig/Hadoop integration working, go with that. I ran into many small issues getting the integration working with just the right version of Hadoop/Pig/and Cassandra 2.0.x

What are the Pros and Cons According to your experience? Many thanks and Regards
