> Queue ACLs work bottom up. The first check is made at the leaf queue. If the
> ACL at that level does not allow access we go up one level and check that
> level. That process is repeated until we hit the top in the form of the root
> queue. If at any level we are allowed to submit or administer then the action
> is allowed and we stop reversing up the tree.
> {quote}
> Bottom up is a surprise behavior. Most queue related checking works top down.
> We should add this into Fair Scheduler Doc. In addition, maybe link the doc
> to Java Doc of AllocationFileLoaderService#getDefaultPermissions so that it
> won't be too confusing.
