Qian Zhang commented on MESOS-7402:
-----------------------------------
I see, thanks [~guoger]. So basically we should check the allocation of the
virtual node ({{a/.}}) against its own quota (60) rather than its parent's
quota (100). With the current implementation of allocator, it seems not easily
to get a virtual node's quota since {{HierarchicalAllocatorProcess.quotas}} is
a hashmap, maybe we could change it to a tree so that we can easily calculate
the quota of virtual node?
> Allocated quota of a child role should be also charged on all ancestors of
> that role

> Consider following case: role {{a}} is quota'd with resource 100, role
> {{a/b}} is quota'd with resource 40. In current implementation, quota of
> parent role is actually the aggregation of quota in whole subtree, including
> itself. Therefore, the internal node of {{a}} is actually quota'd with 60,
> instead of 100. In another word, allocation made for quota of {{a/b}} should
> also be charged from the quota of its parent.
