Jie Yu updated MESOS-3252:
--------------------------
Assignee: Paul Brett
> Ignore no statistics condition for containers with no qdisc
> -----------------------------------------------------------
>
> Key: MESOS-3252
> URL: https://issues.apache.org/jira/browse/MESOS-3252
> Project: Mesos
> Issue Type: Bug
> Components: isolation
> Reporter: Paul Brett
> Assignee: Paul Brett
>
> In PortMappingStatistics::execute, we log the following errors to stderr if
> the egress rate limiting qdiscs are not configured inside the container.
> {code}
> Failed to get the network statistics for the htb qdisc on eth0
> Failed to get the network statistics for the fq_codel qdisc on eth0
> {code}
> This can occur because of an error reading the qdisc (statistics function
> return an error) or because the qdisc does not exist (function returns none).
>
> We should not log an error when the qdisc does not exist since this is normal
> behaviour if the container is created without rate limiting. We do not want
> to gate this function on the slave rate limiting flag since we would have to
> compare the behaviour against the flag value at the time the container was
> created.
