Andrew Schwartzmeyer commented on MESOS-6892:
---------------------------------------------
The use of `os::pids`, `os::processes`, and `os::pstree` may no longer be
necessary. We'll probably end up removing them for Windows, but I deem it as
separate work.
> Reconsider process creation primitives on Windows

> Key: MESOS-6892
> URL: https://issues.apache.org/jira/browse/MESOS-6892
> Project: Mesos
> Issue Type: Bug
> Components: stout
> Reporter: Alex Clemmer
> Assignee: Andrew Schwartzmeyer
> Labels: microsoft
>
> Windows does not have the same notions of process hierarchies as Unix, and so
> killing groups of processes requires us to make sure all processes are
> contained in a job object, which acts something like a cgroup. This is
> particularly important when we decide to kill a task, as there is no way to
> reliably do this unless all the processes you'd like to kill are in the job
> object.
> This causes us a number of issues; it is a big reason we needed to fork the
> command executor, and it is the reason tasks are currently unkillable in the
> default executor.
> As we clean this issue up, we need to think carefully about the process
> governance semantics of Mesos, and how we can map them to a reliable, simple
> Windows implementation.
