Owen O'Malley commented on HADOOP-1425:
---------------------------------------
I would make the trivial example be:
{code}
public class Foo {
public static void main(String[] argv) throws Exception {
JobClient.runJob(new OptionParser().fillInConfiguration(new JobConf(),
argv));
}
}
{code}
JobClient likely should have another method that calls System.exit with the
result of the run, but that is neither here nor there. By making it a straight
library, you have made the code easier to understand with well separated areas
of concern. There are also easy ways to add additional parameters, etc.
