Ian Downes created MESOS-1149:
---------------------------------
Summary: SlaveRecovery.Reboot test doesn't reap executor
Key: MESOS-1149
URL: https://issues.apache.org/jira/browse/MESOS-1149
Project: Mesos
Issue Type: Bug
Components: test
Affects Versions: 0.18.0
Reporter: Ian Downes
The executor pid should be reaped after the slave is "rebooted" and before the
next slave is started to correctly simulate a host reboot, otherwise there's a
race and it may be present (as a zombie) when the test completes.

-------------------------------------------------------------
We cannot run any cgroups tests that require mounting
hierarchies because you have the following hierarchies mounted:
/sys/fs/cgroup/cpu, /sys/fs/cgroup/cpuacct, /sys/fs/cgroup/freezer,
/sys/fs/cgroup/memory
We'll disable the CgroupsNoHierarchyTest test fixture for now.
