    In Hadoop 2, the components are split into modules and so we now have multiple jars. For writing mapreduce programs, it should be enough to simply depend on the hadoop-client module/jar. The rest of the transitive dependencies should be pulled in automatically assuming you are using maven or ant/ivy.
