[jira] [Created] (YARN-4752) [Umbrella] FairScheduler: Improve preemption

Karthik Kambatla created YARN-4752:
--------------------------------------

             Summary: [Umbrella] FairScheduler: Improve preemption
                 Key: YARN-4752
                 URL: https://issues.apache.org/jira/browse/YARN-4752
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 2.8.0
            Reporter: Karthik Kambatla


A number of issues have been reported with respect to preemption in FairScheduler along the lines of:
# FairScheduler preempts resources from nodes even if the resultant free resources cannot fit the incoming request.
# Preemption doesn't preempt from sibling queues
# Preemption doesn't preempt from sibling apps under the same queue that is over its fairshare
# ...

Filing this umbrella JIRA to group all the issues together and think of a comprehensive solution.
