Retrieving failure when app terminates abnormally

[Yuliya Feldman]

Hello there,

I am trying to use async APIs to start/stop Twill managed Yarn Application.

I am using onRunning() and onTerminated() APIs for this, but I don't see a
way of retrieving an error in case of failure

public void onTerminated(final Runnable runnable, Executor executor) {
  this.addListener(new ServiceListenerAdapter() {
    public void failed(State from, Throwable failure) {
      runnable.run();
    }

    public void terminated(State from) {
      runnable.run();
    }
  }, executor);
}


Is there is a way of retrieving "Throwable failure" ?

Or am I using wrong APIs?

Thanks
