> FairScheduler: Parent queues with 'Fair' policy should compute shares of all

> Key: YARN-4212
> URL: https://issues.apache.org/jira/browse/YARN-4212
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Arun Suresh
> Assignee: Arun Suresh

> Attachments: YARN-4212.1.patch
>
>
> The Fair Scheduler, while performing a {{recomputeShares()}} during an
> {{update()}} call, uses the parent queues policy to distribute shares to its
> children.
> If the parent queues policy is 'fair', it only computes weight for memory and
> sets the vcores fair share of its children to 0.
> Assuming a situation where we have 1 parent queue with policy 'fair' and
> multiple leaf queues with policy 'drf', Any app submitted to the child queues
> with vcore requirement > 1 will always be above fairshare, since during the
> recomputeShare process, the child queues were all assigned 0 for fairshare
> vcores.
