> Key: YARN-6808
> URL: https://issues.apache.org/jira/browse/YARN-6808
> Project: Hadoop YARN
> Issue Type: New Feature
> Reporter: Arun Suresh

> This is based on discussions with [~kasha] and [~kkaranasos].
> Currently, when a Queues goes over capacity, apps on starved queues must wait either for containers to complete or for them to be pre-empted by the scheduler to get resources.
> 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.
