      Description

      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.
