This is my case:
My cgroups_root of mesos-slave is some_user/mesos under /sys/fs/cgroup。
It happens that this some_user dir may be gone for some unknown reason, in which case I can no longer create any cgroup and any task will fail.
So I would like to change
in CgroupsIsolatorProcess::prepare in src/slave/containerizer/mesos/isolators/cgroups/cgroups.cpp.
However, I'm not sure if there's any potential problem doing so. Any advice?
