> 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.
