---------------------------------
Summary: 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
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.
