> Throttle Localization for Opportunistic Containers in the NM

> Key: YARN-7547
> URL: https://issues.apache.org/jira/browse/YARN-7547
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Arun Suresh
> Assignee: Abhishek Modi
> Priority: Major
>
> Currently, Localization is performed before the container is queued on the
> NM. It is possible that a barrage of Opportunsitic containers can prevent
> Guaranteed containers from starting. This can be avoided by throttling
> Localization Requests for opportunistic containers - for eg. if the number of
> Queued containers is > x, then don't start localization for new Opp
> containers.
