Subject [jira] [Commented] (YARN-3867) ContainerImpl changes to support container resizing
Date Fri, 24 Jul 2015 22:13:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14641156#comment-14641156

Jian He commented on YARN-3867:
-------------------------------

Had an offline discussion with Wangda,  given that the current update logic is fairly light
weighted and even the nm-state-store operation happens synchronously at user-level API, we
may also synchronously update the container size on the increaseContainersResource call ?
The benefit is that user can get fast notification that the container is re-sized immediately
when the call returns. We can always re-visit this part if this really becomes a bottleneck
as the API itself won't change either ways.
