Guangya Liu commented on MESOS-3338:
------------------------------------

[~mcypark] I see that allocator has an API HierarchicalAllocatorProcess<RoleSorter, FrameworkSorter>::updateAvailable, but this API was not called by master now, can you please show some comments on this? Thanks.

> Dynamically reserved resources should be considered used or allocated and hence reflected in Mesos bookkeeping structures and {{state.json}}.
> I expanded the {{ReservationTest.ReserveThenUnreserve}} test with the following section:
> {code}
>   // Check that the Master counts the reservation as a used resource.
>   {
>     Future<process::http::Response> response =
>       process::http::get(master.get(), "state.json");
>     AWAIT_READY(response);
>     Try<JSON::Object> parse = JSON::parse<JSON::Object>(response.get().body);
>     ASSERT_SOME(parse);
>     Result<JSON::Number> cpus =
>       parse.get().find<JSON::Number>("slaves[0].used_resources.cpus");
>     ASSERT_SOME_EQ(JSON::Number(1), cpus);
>   }
> {code}
> and got
> {noformat}
> ../../../src/tests/reservation_tests.cpp:168: Failure
> Value of: (cpus).get()
>   Actual: 0
> Expected: JSON::Number(1)
> Which is: 1
> {noformat}
