Subject [jira] [Updated] (YARN-1803) Signal container support in nodemanager
Date Sat, 03 May 2014 02:51:14 GMT

     [ https://issues.apache.org/jira/browse/YARN-1803?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ming Ma updated YARN-1803:

    Attachment: YARN-1803.patch

Here is the patch to support signal container functionality in node manager.

1. NodeStatusUpdater will send  ContainerManagerEventType.SIGNAL_CONTAINERS to ContainerManager
when it receives notification from RM. That will be covered under https://issues.apache.org/jira/browse/YARN-1805.
2. After ContainerManager receives ContainerManagerEventType.SIGNAL_CONTAINERS, it will notify
ContainersLauncher via ContainersLauncherEventType.SIGNAL_CONTAINER and eventually deliver
the request to ContainerExecutor.
3. ContainerExecutor's signalContainer method is modified to take OS-independent SignalContainerCommand.

Note, the patch also includes YARN-1897 so that jenkins can build the patch.

> It could include the followings.
> 1. ContainerManager is able to process a new event type ContainerManagerEventType.SIGNAL_CONTAINERS
coming from NodeStatusUpdater and deliver the request to ContainerExecutor.
> 2. Translate the platform independent signal command to Linux specific signals. Windows
support will be tracked by another task.
