[jira] [Created] (YARN-568) FairScheduler: support for work-preserving preemption

Carlo Curino created YARN-568:
---------------------------------

             Summary: FairScheduler: support for work-preserving preemption 
                 Key: YARN-568
                 URL: https://issues.apache.org/jira/browse/YARN-568
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: scheduler
            Reporter: Carlo Curino


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.
