Subject [jira] [Created] (MESOS-6145) Isolator namespaces/pid is leaking mounts
Date Fri, 09 Sep 2016 11:48:20 GMT
Stephan Erb created MESOS-6145:
----------------------------------

             Summary: Isolator namespaces/pid is leaking mounts
                 Key: MESOS-6145
                 URL: https://issues.apache.org/jira/browse/MESOS-6145
             Project: Mesos
          Issue Type: Bug
          Components: containerization, isolation, security
            Reporter: Stephan Erb


As the operator of a Mesos cluster, I would like every container/executor to run in a single
PID namespace, so that one task cannot see what else is running on the same host.

The existing {{namespaces/pid}} isolator seems to provide this feature. However, it seems
like it is leaking files. I have exactly one task running currently, but there are still left
overs from earlier invocations
