Resolution: Not A Problem
This is more an AM / application specific change and should not be part of core
YARN
> AM policies for choosing type of containers
> -------------------------------------------
>
> Key: YARN-2887
> URL: https://issues.apache.org/jira/browse/YARN-2887
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager, resourcemanager
> Reporter: Konstantinos Karanasos
>
> Each AM can employ policies that determine what type of container
> (guaranteed-start or queueable) should be requested for each task.
> An example policy may be to use only guaranteed-start or only queueable
> containers, or to randomly pick a percentage of the requests to be queueable,
> or to choose the container type based on the characteristics of the tasks.
