I am currently reading Hadoop in Action .The book is very good, however it uses hadoop 1.2.1 to explain and showcase all the examples. But, I am using hadoop 2.2.0.
Does anybody know where I can find a full documentation about hadoop api changes ? and a simple mapping between 1.2.1 and 2.2.0 ?
For examples
DataJoinMapperBase, DataJoinReducerBase, and TaggedMapOutput
Does not present in 2.2.0 and I am looking for there counterparts in 2.2.0
