preserving failed containers

Hi Devs,

Is there some config variable to preserve appcache directories in case of
failed containers?
MapReduce 1.0 had feature where one could preserve failed tasks so as to
see state of local directories on node.
Looking at DefaultContainerExecutor I could not see any such option for
YARN. I am trying to debug a case where one of my task fails in container
launch phase.
Container launch script dies with exit code 1 but nothing is logged. What
trick do you use to debug such failures.
