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.
