---------------------------------
Summary: Handle cgroups v2 hierarchy when parsing
/proc/self/cgroups.
Key: MESOS-7969
URL: https://issues.apache.org/jira/browse/MESOS-7969
Project: Mesos
Issue Type: Bug
Affects Versions: 1.2.3, 1.3.2, 1.5.0, 1.4.1
Reporter: Kapil Arya
Assignee: Kapil Arya
Cgroups v2 hierarchies don't list the "controllers" field (e.g.,
"0::/user.slice/user-1000.slice/session-5.scope) is empty [1] and hence the
cgroup parser failes. We should simply skip over fields with empty controller
field.
