MENG DING commented on YARN-1644: --------------------------------- I think the race condition is still there. Even though the resource is updated synchronously, NM re-registration can still happen between the time the increase action is accepted, and the time the resource is updated. We still need a mechanism for RM to know that there is pending increase going on in NM, don't we? > RM-NM protocol changes and NodeStatusUpdater implementation to support > container resizing > ----------------------------------------------------------------------------------------- > > Key: YARN-1644 > URL: https://issues.apache.org/jira/browse/YARN-1644 > Project: Hadoop YARN > Issue Type: Sub-task > Components: nodemanager > Reporter: Wangda Tan > Assignee: MENG DING > Attachments: YARN-1644-YARN-1197.4.patch, > YARN-1644-YARN-1197.5.patch, YARN-1644.1.patch, YARN-1644.2.patch, > YARN-1644.3.patch, yarn-1644.1.patch > > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
