> Users often complain about the XML they have to write for Oozie jobs.  It would be nice if they could write them in something like Java, but we don't want to have to maintain a separate Java API for this.  I was looking around and saw that JAXB might be the right thing here.  From what I can tell, it lets you create Java classes from XSD schemas.  So, we should be able to auto-generate a Java API for writing Oozie jobs, without having to really maintain it.
> We should investigate if this is feasible and, if so, implement it.
