To answer more precisely: you should read all three. In theory, mapreduce-specific questions should be directed to mapreduce-user, and hdfs-specific questions should be directed to hdfs-user. common-user is technically just for questions about the "common" code in Hadoop, e.g. the I/O serialization subsystem, things like SequenceFile, etc. In practice, common-user is sort of a catch-all where you'll find lots of questions about all aspects of Hadoop though.
