> FairScheduler headroom calculation doesn't consider maxResources for Fifo and
> FairShare policies
> ------------------------------------------------------------------------------------------------
>
> Key: YARN-3485
> URL: https://issues.apache.org/jira/browse/YARN-3485
> Project: Hadoop YARN
> Issue Type: Bug
> Components: fairscheduler
> Affects Versions: 2.7.0
> Reporter: Karthik Kambatla
> Assignee: Karthik Kambatla
> Priority: Critical
> Attachments: yarn-3485-1.patch, yarn-3485-2.patch,
> yarn-3485-prelim.patch
>
>
> FairScheduler's headroom calculations consider the fairshare and
> cluster-available-resources, and the fairshare has maxResources. However, for
> Fifo and Fairshare policies, the fairshare is used only for memory and not
> cpu. So, the scheduler ends up showing a higher headroom than is actually
> available. This could lead to applications waiting for resources far longer
> than then intend to. e.g. MAPREDUCE-6302.
