Dear Whom-ever-is-responsible

While I passed the map-reduce/YARN course, it would be really useful to get feedback on the answers I got wrong on the final. I understand that if there are a limited amount of potential questions, you don't want a free copy of all answer floating around the net. Unfortunately, at the moment I am unsure if I got a question incorrect because of actually not knowing the proper answer, or due to lack of clarity in the question (which was apparent for several)/misinterpretation.

Just FYI
