----------------------------------------
Summary: Document the locality effect of preemption timeouts in
FairScheduler when mapred.fairscheduler.preemption is off
Key: MAPREDUCE-4986
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4986
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: contrib/fair-share, documentation
Affects Versions: 1.1.1
Reporter: Gera Shegalov
fair_scheduler.xml does not mention the delay scheduling algorithm.
Furthermore, it does not explain that in getAllowedLocalityLevel the preemption
timeouts are used to disable the locality delay scheduling for the starved pool
when mapred.fairscheduler.preemption=false (default).
