             Summary: ContainerizerTest::setUp should check all cgroup subsystems to determine base hierarchy
                 Key: MESOS-1531
                 URL: https://issues.apache.org/jira/browse/MESOS-1531
             Project: Mesos
          Issue Type: Bug
          Components: test
    Affects Versions: 0.20.0
            Reporter: Ian Downes


Current code looks a just one subsystem (from the hashset) to work out the base hierarchy. This fails if that subsystem is not mounted but others already are, since it will try to mount the unmounted subsystem at the test hierarchy. Instead, the code should go through *all* subsystems to find the first that is mounted. Only if none are mounted then it should use the TEST_CGROUPS_HIERARCHY.
