Jie Yu created MESOS-3814:
-----------------------------
Summary: Add checks to make sure isolators and the launcher are
compatible.
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
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.
