That is a pretty wide question. What kind of depth are you seeking in an answer? Also, it
has been asked before numerous times in different forms -- do try searching too! :)

To begin with, have you gone over the elementary articles such as the architecture guides
and tutorials we carry at http://hadoop.apache.org/common/docs/current/, the still-relevant
YDN Hadoop Tutorial that covers a range of things at http://developer.yahoo.com/hadoop/tutorial/
and some of the videos available at http://www.cloudera.com/resources/Training/ (there are
loads out there, and a few sites also organize these).

After having done that, try checking out sources and read up from the API points of code that
you've used often when writing FS clients or jobs. From there its just a never ending fall
down the rabbit hole.
