Subject [jira] [Commented] (MESOS-6145) Isolator namespaces/pid is leaking mounts
Date Fri, 16 Sep 2016 01:00:41 GMT

Jie Yu commented on MESOS-6145:
-------------------------------

OK, I'll take some time to fix the isolator. It might be a breaking change as I want to change
some of the ways we do checkpointing.

>             Project: Mesos
>          Issue Type: Bug
>          Components: containerization, isolation, security

> As the operator of a Mesos cluster, I would like every container/executor to run in a
single PID namespace, so that a 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
