Jie Yu commented on MESOS-2652:
-------------------------------
Instead of using a hierarchical structure, I am wondering if it's possible to
still keep the existing flattened structure? We can set cpu.shares of those
revokable containers to be very small (or the shares of the normal container to
be very large) so that it's still negligible even if there are many revokable
containers.

> The CPU isolator needs to properly set limits for revocable and non-revocable
> containers.
> The proposed strategy is to use a two-way split of the cpu cgroup hierarchy
> -- normal (non-revocable) and low priority (revocable) subtrees -- and to use
> a biased split of CFS cpu.shares across the subtrees, e.g., a 20:1 split
> (TBD). Containers would be present in only one of the subtrees. CFS quotas
> will *not* be set on subtree roots, only cpu.shares. Each container would set
> CFS quota and shares as done currently.
