Karthik Kambatla updated YARN-4077:
-----------------------------------
Component/s: fairscheduler
> FairScheduler Reservation should wait for most relaxed scheduling delay
> permitted before issuing reservation
> ------------------------------------------------------------------------------------------------------------
>
> Key: YARN-4077
> URL: https://issues.apache.org/jira/browse/YARN-4077
> Project: Hadoop YARN
> Issue Type: Bug
> Components: fairscheduler
> Reporter: Anubhav Dhoot
>
> Today if an allocation has a node local request that allows for relaxation,
> we do not wait for the relaxation delay before issuing the reservation. This
> can be too aggressive. Instead we should allow the scheduling delays of
> relaxation to expire before we choose to allow reserving a node for the
> container. This allows for the request to be satisfied on a different node
> instead.
