> Key: YARN-5860
> URL: https://issues.apache.org/jira/browse/YARN-5860
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Arun Suresh
> Assignee: Arun Suresh
> Fix For: 2.9.0, 3.0.0
>
>
> Currently the queuing framework (introduced in YARN-2877) in the NM that
> handles opportunistic containers, are pre-empts opportunistic containers only
> when resources are need to start guaranteed containers.
> It currently does not handle situations where a guaranteed container
> resources have been increased. Conversely, if a guaranteed (or opportunistic)
> container's resources have been decreased, the NM must start queued
> opportunistic containers waiting on the newly available resources.
