Subject [jira] [Commented] (YARN-4528) decreaseContainer Message maybe lost if NM restart
Date Tue, 05 Jan 2016 00:26:40 GMT

    [ https://issues.apache.org/jira/browse/YARN-4528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15082083#comment-15082083

MENG DING commented on YARN-4528:

Honestly I don't think the design needs to be changed, unless other people think differently.
As you said, this RARELY, if ever happens. Also, we acknowledged that AM only issues decrease
request when it knows that a container doesn't need the original amount of resource, and a
failed decrease message in NM is not at all fatal (unlike a failed increase message, which
may cause the container to be killed by the resource enforcement).
