Yan Xu created MESOS-891:
----------------------------
Summary: Cgroups cleanup() should wait for all attached subsystems
to be detached
Key: MESOS-891
URL: https://issues.apache.org/jira/browse/MESOS-891
Project: Mesos
Issue Type: Bug
Reporter: Yan Xu
Assignee: Yan Xu
Fix For: 0.16.0
Otherwise the subsystems could still be attached when cleanup() exits and
subsequent mount can fail.
This was observed in:
SlaveRecoveryTest/1.SchedulerFailover: assertion failure at
https://github.com/apache/mesos/blob/9efb009d55e18e6a34bb25e6870c261c894551b7/src/tests/mesos.cpp#L263
despite that `cgroups::hierarchy(subsystems)` which reads from `/proc/mounts`
returns None.
