In the example MultiFileWordCount.java (hadoop-0.17.0), what happens when the statement JobClient.runJob(job); is executed. What methods will be called in sequence?
You really should be running 0.17.2 (or the upcoming 0.17.3) instead of 0.17.0. There are some important bug fixes.
It is a long and complicated process. Fundamentally, it submits your job to the cluster, but there are a lot of methods in a lot of contexts to make it happen. If you have a specific requirement, I suggest you look at the source code.
