src/slave/containerizer/mesos/isolators/namespaces/uts.cpp (lines 70 - 79) <https://reviews.apache.org/r/53627/#comment227830> Wouldn't this conflict with what we are doing in the `network/cni` isolator. For containers with a `NetworkInfo` we end up creating a new UTS namespace in the `network/cni` isolator. More importantly the isolator sets the hostname to the `ContianerID` and also sets this information up in `/etc/hosts` for DNS to resolve correctly. Since the `network/cni` isolator is enabled by default, this would end up conflicting with the UTS isolator. - Avinash sridharan On Nov. 28, 2016, 5:07 p.m., James Peach wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
