-------------------------------------
Summary: PortMappingIsolatorTest fail when no namespaces are set.
Key: MESOS-4643
URL: https://issues.apache.org/jira/browse/MESOS-4643
Project: Mesos
Issue Type: Bug
Environment: Linux Kernel 3.19.0-49-generic,
libnl-3.2.27
Reporter: Till Toenshoff
Priority: Minor
Currently our network isolator tests fail with the following output on a Ubuntu
14.04 VM.
{noformat}
[02:10:15][Step 8/8] [ RUN ]
PortMappingIsolatorTest.ROOT_NC_ContainerToContainerTCP

Failure

or directory

The machine has no network namespaces set, hence {{/var/run/netns}} does not
exist.
We should help users understanding this prerequisite or maybe even get these
things in a fixture.
