I need to chain two MapReduce jobs. I used JobControl to set job2 as dependent of job1. It works, output files are created!! But it doesn\'t stop! In the shell it remains in
I essentially did what Pietro alluded to above.
public class JobRunner implements Runnable {
private JobControl control;
public JobRunner(JobControl _control) {
this.control = _control;
}
public void run() {
this.control.run();
}
}
and in my map/reduce class I have:
public void handleRun(JobControl control) throws InterruptedException {
JobRunner runner = new JobRunner(control);
Thread t = new Thread(runner);
t.start();
while (!control.allFinished()) {
System.out.println("Still running...");
Thread.sleep(5000);
}
}
in which I just pass the jobControl object.
