> [Umbrella] Container preemption using OPPORTUNISTIC containers
> --------------------------------------------------------------
>
> Key: YARN-6828
> URL: https://issues.apache.org/jira/browse/YARN-6828
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Arun Suresh
> Assignee: Arun Suresh
>
> This is based on discussions with [~kasha] and [~kkaranasos].
> Currently, the YARN schedulers selects containers for preemption only in
> response to a starved queue / app's request. We propose to allow the
> Schedulers to mark containers that are allocated over queue
> capacity/fair-share as Opportunistic containers.
> This JIRA proposes to allow Schedulers to:
> # Allocate all containers over the configured queue capacity/weight as
> OPPORTUNISTIC.
> # Auto-promote running OPPORTUNISTIC containers of apps as and when their
> GUARANTEED containers complete.
