> In the attached patch, we modified the FairScheduler to substitute its
> preemption-by-killling with a work-preserving version of preemption (followed
> by killing if the AMs do not respond quickly enough). This should allows to
> run preemption checking more often, but kill less often (proper tuning to be
> investigated). Depends on YARN-567 and YARN-45, is related to YARN-569.
