Subject [jira] [Created] (MAPREDUCE-4468) Encapsulate FairScheduler preemption logic into helper class
Date Fri, 20 Jul 2012 19:05:36 GMT
Ryan Hennig created MAPREDUCE-4468:

             Summary: Encapsulate FairScheduler preemption logic into helper class
                 Key: MAPREDUCE-4468
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4468
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: scheduler
            Reporter: Ryan Hennig
            Priority: Minor
             Fix For: 2.1.0-alpha

I've extracted the preemption logic from the Fair Scheduler into a helper class so that FairScheduler
is closer to following the Single Responsibility Principle.  This may eventually evolve into
a generalized preemption module which could be leveraged by other schedulers.
