---------------------------------------
I think that this feature request has already been addressed. The JobClient can
already allow programmatic submission and monitoring of jobs.
> Submittable interface, for the ability to execute and monitor jobs from a

> Hi,
> We wish to add the following interface:
> interface Submittable{
> RunningJob submitJob(JobConf jc);
> }
> Currently there is no clean way to monitor a submitted job programatically,
> one way would be to call main, and parse the output to figure out Jobid, and
> then monitor it using a JobClient. Currently the only way RunJar can run a
> Class in a Jar file is using main.invoke().
> The purpose of this interface is to be able to programatically call the class
> that extends this interface via another Class (similar to RunJar) and still
> be able to monitor it like JobClient does.
> Essentially, all the functionality within a main class would be encapsulated
> within this method such as implementing constraints between various user
> defined job.xml keys.
> The purpose of main would be reduced to parsing arguments, setting the
> JobConf and calling this function.
