Jian He commented on YARN-4597:
-------------------------------
I see.. thanks for looking into it.. I guess the killedBeforeStart flag could
be avoided, by calling "container.isMarkedToKill()" directly in the
handleContainerExitCode method like below ?
{code}
if (!container.isMarkedToKill()) {
dispatcher.getEventHandler().handle(
new ContainerExitEvent(containerId,
ContainerEventType.CONTAINER_KILLED_ON_REQUEST, exitCode,
diagnosticInfo.toString()));
}
{code}
> Add SCHEDULE to NM container lifecycle

> Currently, the NM immediately launches containers after resource
> localization. Several features could be more cleanly implemented if the NM
