Carlo Curino updated YARN-568:
------------------------------
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.
