Subject [jira] [Commented] (YARN-5221) Expose UpdateResourceRequest API to allow AM to request for change in container properties
Date Mon, 29 Aug 2016 19:48:21 GMT

    [ https://issues.apache.org/jira/browse/YARN-5221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15446874#comment-15446874

Subru Krishnan commented on YARN-5221:

Thanks [~asuresh] for addressing my feedback. 

I feel few of the checkstyle warnings can be fixed.

When I was making a final pass on the patch, I realized that in {{RMServerUtils::validateAndSplitUpdateResourceRequests}},
we are only validating update requests within the current _AllocateRequest_ but we should
be checking against global outstanding update asks as the allocate protocol is asynchronous.
I am fine with addressing this in a separate JIRA along with the refactoring work based on
your comment [above|https://issues.apache.org/jira/browse/YARN-5221?focusedCommentId=15442729].
