> Key: MESOS-3814
> URL: https://issues.apache.org/jira/browse/MESOS-3814
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 0.26.0
> Reporter: Jie Yu
> Assignee: Artem Harutyunyan
>
> There's a recent change regarding the picking of which launcher (Linux or
> Posix) to use
> https://reviews.apache.org/r/39604
> In our environment, cgroups are not auto-mounted after reboot. We rely on
> Mesos itself to mount all relevant cgroups hierachies.
> After the reboot, the above patch detects that 'freezer' hierarchy is not
> mounted, therefore, decided to use the Posix launcher (if --launcher is not
> specified explictly).
> Port mapping isolator requires network namespace to be created for each
> container (thus requires Linux launcher). But we don't have a check to verify
> that launcher and isolators are compatible.
> Slave thus starts fine and task failed with weird error like:
> {noformat}
> Collect failed: Failed to create the ingress qdisc on mesos61099: Link
> 'mesos61099' is not found.
> {noformat}
> It does take us quite a few time to figure out the root cause.
