failed in Ubuntu 14.04
Just a problem when investing [MESOS-3349
PersistentVolumeTest.AccessPersistentVolume fails when run as
root.|https://issues.apache.org/jira/browse/MESOS-3349]
In LinuxFilesystemIsolatorProcess::cleanup, when we read mount table and
umount. The order should use reverse order. Suppose our mount order is
{code}
mount /tmp/a /tmp/b
mount /tmp/c /tmp/b/c
{code}
Currently we umount logic in cleanup is
{code}
umount /tmp/b
umount /tmp/b/c <- Wrong
{code}
This is the reason why ROOT_VolumeFromHostSandboxMountPoint failed.
