Benjamin Mahler created MESOS-414:
-------------------------------------

             Summary: CgroupsNoHierarchyTest should be disable when a hierarchy is mounted.
                 Key: MESOS-414
                 URL: https://issues.apache.org/jira/browse/MESOS-414
             Project: Mesos
          Issue Type: Bug
            Reporter: Benjamin Mahler
            Assignee: Benjamin Hindman


See below, we currently fail the test when there's a hierarchy mounted. Rather, we should keep the message, but disable the test.

The logic for determining whether we can run the test already exists, this is how we determine whether to print the message below.

[----------] 1 test from CgroupsNoHierarchyTest
-------------------------------------------------------------
We cannot run any cgroups tests that require mounting
hierarchies because you have the following hierarchies mounted:
/cgroup
You can either unmount those hierarchies, or disable
this test case (i.e., --gtest_filter=-CgroupsNoHierarchyTest.*).
-------------------------------------------------------------
[ RUN      ] CgroupsNoHierarchyTest.ROOT_CGROUPS_MountUnmountHierarchy
../../src/tests/cgroups_tests.cpp:250: Failure
cgroups::mount(TEST_CGROUPS_HIERARCHY, "cpu,memory"): 'cpu' is already attached to another hierarchy
[  FAILED  ] CgroupsNoHierarchyTest.ROOT_CGROUPS_MountUnmountHierarchy (1 ms)
