Johan Oskarsson updated HADOOP-1433:

Cleaned up the findbugs issue. Also fixed most codestyle problems (in some cases I kept the
style of the current source).

Comments are more then welcome.

> A simple way of specifying the job priority in the JobConf and perhaps even change it
during runtime via the jobtracker web ui would help a lot.
