FairScheduler can preempt the same task many times
--------------------------------------------------
Key: MAPREDUCE-1974
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1974
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Scott Chen
Assignee: Scott Chen
In FairScheduler.preemptTasks(), tasks are collected from
JobInProgress.runningMapCache.
But tasks repeat multiple times in JobInProgress.runningMapCache (on rack,
node and cluster).
This makes FairScheduler preempt the same task many times.
