non-quota roles.

Fix it, then Ship it!
Looks good! Just some comments related to comments and naming, no code changes, so I can take care of these for you and get this committed!

Looks like we could add the same structure to this comment as I suggested in the previous review.

Some symmetry here would be helpful:
roleReservationQuantities vs
roleAllocatedReservationQuantities
The maps:
reservationScalarQuantities vs
allocatedReservationScalarQuantites
Probably it makes sense to be consistent with "quantities" vs "scalarQuantites"?

Maybe a little bit more of an explanation of why we count reservations?
```
// We charge a role against its quota by considering its
// allocation as well as any unallocated reservations
// since reservations are bound to the role. In other
// words, we always consider reservations as consuming
// quota, regardless of whether they are allocated.
// The equation used here is:
//
// Consumed Quota = reservations + unreserved allocation
// = reservations + (allocation - allocated reservations)
//
// This is a __quantity__ with no meta-data.
Resources resourcesChargedAgainstQuota =
roleReservationScalarQuantities +
(getQuotaRoleAllocatedResources(role) -
roleAllocatedReservationScalarQuantities);
```
src/master/allocator/mesos/hierarchical.cpp
Lines 1658-1663 (patched)
<https://reviews.apache.org/r/64304/#comment272054>
How about?
```
// If quota for the role is considered satisfied, then we only
// further allocate reservations for the role.
//
// More precisely, we stop allocating unreserved resources if at
// least one of the resource guarantees is considered consumed.
// This technique prevents gaming of the quota allocation,
// see MESOS-6432.
```
I feel like "satisfied" is explained in the second paragraph, and this updates that paragram to say "considered consumed" which matches up with the comment about what we consider consumed against quota.

Just an observation, unlike the tracked map, this map will contain role entries with empty resources. Don't think we need to write this down, just an inconsistency between the two that may crop up later (e.g. if this map gets moved to a allocator global map).

Great to see this getting fixed!
First pass over just the non-testing code. Can you split out the test into a separate patch?

<https://reviews.apache.org/r/64304/#comment271855>
s/every allocation/every allocation run/
You might want to clarify that given the other TODO below this one, the plan is to remove the discrepancy between what the sorter considered allocated and what we'd like to count as allocated for fair sharing and quota. i.e. we should be able to simplify this and just retrieve what the role's "allocation" is in the sorter

Parameterized the test for both dynamic reservation and static reservation.
The first test ensures that quota limit does not get exceeded in the presence of unallocated-reservation. (expect no pending allocation)
The second test ensures that when a role’s reserved resources gets allocated and (by that time) if its quota still has not been fully satisfied, it can get unreserved resources to meet its quota. (expect allocation of unreserved resources).
I do not think you proposed test checks that. I clarified the comments and test name.

This test is also just dynamic reservations, so the same comment above applies. Maybe we need to parameterize these tests based on whether to use static or dynamic reservation?
It's also not clear to me why we need both tests, instead of just a single test.
E.g.
quota = R
add agent 1 with R resources, reserve them, decline forever
add agent 2 with R resources, they should not be allocated
revive
should only get agent 1 resources offered
trigger another allocation cycle (to make sure it's enforced across cycles)
agent 2 should not be offered to the role

I think ultimately, the sorter needs to consider reserved resources as "allocated", do you have any TODO related to this or any tickets?
I guess the "unfairly satisfy guarantees" in [MESOS-4527](https://issues.apache.org/jira/browse/MESOS-4527) means that we couldn't close this ticket until we also track the reservations in the sorters, which will affect the code here (i.e. you might not need to track the reservations separately?)
Also, we would need a ticket for reservations breaking fairness for the non-quota roles, I don't think there is one yet.

Can you add a note here about [MESOS-7099](https://issues.apache.org/jira/browse/MESOS-7099)?
src/master/allocator/mesos/hierarchical.cpp
Lines 1797-1798 (patched)
<https://reviews.apache.org/r/64304/#comment271080>

```
// TODO(mzhu): Breaking early here means that we may leave reservations

```
