API difference between hadoop branch1 and branch2?
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!

Best Regards,
Li Yu

Hi Li Yu,
I don't think it has been published yet, but a document on the MapReduce
changes was recently completed at
https://issues.apache.org/jira/browse/MAPREDUCE-5184.
