Subject [jira] [Commented] (YARN-1972) Implement secure Windows Container Executor
Date Thu, 05 Jun 2014 07:27:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-1972?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14018556#comment-14018556
] 

Remus Rusanu commented on YARN-1972:
------------------------------------

[~vinodkv] About the uniqueness of appid for localizer: it is not unique when multiple tasks
are being localized for the same job, on the same node. Simply running pi with 100 splits
on a 2 node cluster results in many duplicate errors. For task localization should be task_id,
I believe.

> This work item represents the Java side changes required to implement a secure windows
container executor, based on the YARN-1063 changes on native/winutils side. 
> Necessary changes include leveraging the winutils task createas to launch the container
process as the required user and a secure localizer (launch localization as a separate process
running as the container user).
