Alexander Rukletsov created MESOS-6142:
------------------------------------------
Summary: Frameworks may RESERVE for an arbitrary role.
Key: MESOS-6142
URL: https://issues.apache.org/jira/browse/MESOS-6142
Project: Mesos
Issue Type: Bug
Components: allocation, master
Affects Versions: 1.0.0
Reporter: Alexander Rukletsov
Priority: Blocker
Fix For: 1.1.0
The master does not validate that resources from a reservation request have the
same role the framework is registered with. As a result, frameworks may reserve
resources for arbitrary roles.
I've modified the role in [the {{ReserveThenUnreserve}}
test|https://github.com/apache/mesos/blob/bca600cf5602ed8227d91af9f73d689da14ad786/src/tests/reservation_tests.cpp#L117]
to "yoyo" and observed the following in the test's log:
