---------------------------------
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.
