---------------------------------
Summary: Allow isolators to specify required namespaces
Key: MESOS-2884
URL: https://issues.apache.org/jira/browse/MESOS-2884
Project: Mesos
Issue Type: Task
Components: isolation
Reporter: Kapil Arya
Assignee: Kapil Arya
Currently, the LinuxLauncher looks into SlaveFlags to compute the namespaces
that should be enabled when launching the executor. This means that a custom
Isolator module doesn't have any way to specify dependency on a set of
namespaces.
The proposed solution is to extend the Isolator interface to also export the
namespaces dependency. This way the MesosContainerizer can directly query all
loaded Isolators (inbuilt and custom modules) to compute the set of namespaces
required by the executor. This set of namespaces is then passed on to the
LinuxLauncher.
