'slaves' and 'masters' file are generally only required in the master
machine, and only if you are using the start-* scripts supplied with
Hadoop for use with SSH (FAQ has an entry on this) from master.

What do the logs say for the DataNode on the slave? Does it start
successfully? If fs.default.name is set properly in slave's
core-site.xml it should be able to communicate properly if started
(and if the version is not mismatched).
