David Yan commented on YARN-658:
--------------------------------
Vinod, Thanks again for looking into this.
My custom AM is not trapping any system signal, and I don't have
yarn.nodemanager.sleep-delay-before-sigkill.ms set.
The thing is, the exact same code works with Ubuntu 12.04, but not 12.10 or
13.04.
> Command to kill a YARN application does not work with newer Ubuntu versions

> After issuing a KillApplicationRequest, the application keeps running on the
> system even though the state is changed to KILLED. It happens on both Ubuntu
> 12.10 and 13.04, but works fine on Ubuntu 12.04.
