Subject [jira] [Commented] (YARN-2882) Add an OPPORTUNISTIC ExecutionType
Date Sun, 27 Dec 2015 08:16:50 GMT

    [ https://issues.apache.org/jira/browse/YARN-2882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15072089#comment-15072089
] 

Wangda Tan commented on YARN-2882:
----------------------------------

[~kasha],
No worries, since they're new APIs and in trunk only, I think we don't have to revert or post
addendum patch, any user-facing API changes could be added to YARN-4335. Will review YARN-4335
and post comments.

> 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.
