Subject [jira] [Commented] (YARN-2882) Introducing container types
Date Thu, 05 Nov 2015 18:39:27 GMT

    [ https://issues.apache.org/jira/browse/YARN-2882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14992207#comment-14992207

Konstantinos Karanasos commented on YARN-2882:

Thanks for the feedback, [~asuresh].
I will address point (2), and will fix the patch so that it applies to the yarn-2877 branch
I created off apache trunk yesterday.

Moreover, I will make sure we align with YARN-3116 that introduced container types for distinguishing
the AM container.

Regarding the builder pattern, do you think we should address that here or is it better to
create a separate JIRA for having a more principled way to create new instances of resources?

> This JIRA introduces the notion of container types.
> We propose two initial types of containers: guaranteed-start and queueable containers.
> Guaranteed-start are the existing containers, which are allocated by the central RM and
are instantaneously started, once allocated.
> Queueable is a new type of container, which allows containers to be queued in the NM,
thus their execution may be arbitrarily delayed.
