Subject [jira] [Commented] (YARN-1515) Ability to dump the container threads and stop the containers in a single RPC
Date Sat, 10 May 2014 21:57:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-1515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13993762#comment-13993762

Jason Lowe commented on YARN-1515:

I apologize for the long delay in reviewing and resulting upmerge it caused.  Patch looks
good to me with just some minor comments:

- StopContainerRequest#getDumpThreads#getDumpThreads should have javadocs and interface annotations
like the other methods
- Why is StopContainersRequest#getStopRequests marked Unstable but setStopRequests is Stable?
- Nit: dumpThreads is an event-specific field, would be nice to have an AMLauncherCleanupEvent
that takes just the app attempt in the constructor and derives from AMLauncherEvent.
