Subject [jira] [Updated] (YARN-1449) Protocol changes in NM side to support change container resource
Date Sat, 07 Dec 2013 02:44:35 GMT

     [ https://issues.apache.org/jira/browse/YARN-1449?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Wangda Tan updated YARN-1449:
-----------------------------

    Attachment: yarn-1449.3.patch

Attached patch updated according to finalized YARN-1447. I also found it's hard to split NM
protocol changes and implementations (I need leave some stub methods in ContainersManagerImpl,
etc.). So I put API changes and implementation together.

> As described in YARN-1197, we need add API in NM to support
> 1) Add a "changeContainersResources" method in ContainerManagementProtocol
> 2) Can get succeed/failed increased/decreased containers in response of "changeContainersResources"
> 3) Add a "new decreased containers" field in NodeStatus which can help NM notify RM such
changes
