Review request for mesos, Alexander Rukletsov, Jie Yu, and Kevin Klues.
Bugs: MESOS-7504
https://issues.apache.org/jira/browse/MESOS-7504
Repository: mesos
Description
-------
To launch a nested container it might be necessarry to enter parent's
mnt namespace. `getMountNamespaceTarget()` is used for doing that.
Previously, `getMountNamespaceTarget` returned a failure when a
parent's child or grandchild process exited after enumerating child
processes and before getting mnt namespace for the process. Mesos
containerizer launches pre-exec hooks that might exit when calling
`getMountNamespaceTarget` during a subsequent launch of a
nested container. This commit makes `getMountNamespaceTarget` tolerant
to blinking child processes.
