Benjamin Mahler created MESOS-539:
-------------------------------------
Summary: Allow per task cgroup isolation.
Key: MESOS-539
URL: https://issues.apache.org/jira/browse/MESOS-539
Project: Mesos
Issue Type: Improvement
Reporter: Benjamin Mahler
This is applicable for other isolation mechanisms as well, but the general idea
here is to allow executors to isolate each task they run, rather than having
executor-wide isolation for all tasks running underneath it.
One simple way to implement this is to add a 'pid' to the TaskStatus, in order
to inform the slave of the Task pid once it's RUNNING. The cgroups isolator can
then migrate the process to a separate cgroup and ensure the executor cgroup
can interact with all processes in the task cgroup.
This would improve isolation, especially for multi-task executors that start
processes per-task.
