Subject [jira] [Updated] (YARN-4945) [Umbrella] Capacity Scheduler Preemption Within a queue
Date Fri, 19 Aug 2016 17:38:20 GMT

     [ https://issues.apache.org/jira/browse/YARN-4945?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Sunil G updated YARN-4945:
    Attachment: IntraQueuepreemption-CapacityScheduler (Design).pdf

Uploading an initial design doc to start discussions.. Also attaching a work in progress patch
based only on priority for POC.

- Document mainly covers overall idea about intra-queue preemption.
- In this document at design level, I took priority as one item to explain in details. As
more items are added, this can be scaled.
- POC patch also covers priority for now 

I am attaching both in parent jira for common discussions. Thanks [~leftnoteasy]. 
Looping [~eepayne] for more thoughts.
