Chuan Liu commented on YARN-2190:
---------------------------------
bq. 1. what would the implications for the move windows 8 for the API? What
does it mean for server versions and builds?
If we want to continue supporting Windows 7 and Windows Server 2008R2 as
default OS version, I can make Windows 8 build optional. Because Windows 7 does
not support set CPU limits on job objects, the CPU limit feature will be absent
in the Windows 7 build.
bq. 2. something is cutting off all the ASF copyright comments ... probably the
IDE. That'll have the RAT tool complaining. It may be something to ignore
during iterative development , but would need to be fixed before committing
Thanks for pointing out this. I will fix it in the new patch.
bq. 3. would it be possible to have a command line like
Yes. This is a very good suggestion!

> Yarn default container executor on Windows does not set the resource limit on
> the containers currently. The memory limit is enforced by a separate
> monitoring thread. The container implementation on Windows uses Job Object
> right now. The latest Windows (8 or later) API allows CPU and memory limits
> on the job objects. We want to create a Windows container executor that sets
> the limits on job objects thus provides resource enforcement at OS level.
