Subject [jira] [Created] (MESOS-3338) Dynamic reservations are not counted as used resources in the master
Date Mon, 31 Aug 2015 15:53:45 GMT
Alexander Rukletsov created MESOS-3338:
------------------------------------------

             Summary: Dynamic reservations are not counted as used resources in the master
                 Key: MESOS-3338
                 URL: https://issues.apache.org/jira/browse/MESOS-3338
             Project: Mesos
          Issue Type: Bug
          Components: allocation, master
            Reporter: Alexander Rukletsov
            Priority: Minor


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}
