Attachment: YARN-2394-2.patch

Update a patch following the same way as YARN-2395. Each queue inherits 
fairSharePreemptionThreshold from its parent queue if it doesn't configure in 
the allocation file. Will rebase the patch once YARN-2395 is in.

 Fair Scheduler : ability to configure fairSharePreemptionThreshold per queue
 

 Key: YARN-2394
 URL: https://issues.apache.org/jira/browse/YARN-2394
 Project: Hadoop YARN
  Issue Type: New Feature
  Components: fairscheduler
Reporter: Ashwin Shankar
Assignee: Wei Yan
 Attachments: YARN-2394-1.patch, YARN-2394-2.patch


 Preemption based on fair share starvation happens when usage of a queue is 
 less than 50% of its fair share. This 50% is hardcoded. We'd like to make 
 this configurable on a per queue basis, so that we can choose the threshold 
 at which we want to preempt. Calling this config 
 fairSharePreemptionThreshold.
