Dear all, I have some applications used to run on hadoop-1.1.1, and now I'd like to try them out on hadoop-2.0. Code of these application will invoke both MapReduce and HDFS api, so I'd like to know what I need to modify if migrate to hadoop-2.0. Is there any material(doc/link) about the API difference between hadoop-1 and hadoop-2? Any information will be highly appreciated!
