Subject [jira] [Commented] (YARN-2190) Add CPU and memory limit options to the default container executor for Windows containers
Date Fri, 06 Mar 2015 19:13:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-2190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14350742#comment-14350742
] 

Jian He commented on YARN-2190:
-------------------------------

 what I meant is if resource != null and knobs are off,  it'll pass -1 for the memory and
cpu, which is not the  same as the original command.

> 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 add the new options to the executor that can set the
limits on job objects thus provides resource enforcement at OS level.
