Subject [jira] [Commented] (YARN-417) Add a poller that allows the AM to receive notifications when it is assigned containers
Date Tue, 26 Feb 2013 18:04:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13587320#comment-13587320

Karthik Kambatla commented on YARN-417:
---------------------------------------

How about following Netty kind of asynchrony? YARNContainerFuture for waiting purposes, and
onContainerComplete(ContainerStatus) for asynchronous notification?

> Writing AMs would be easier for some if they did not have to handle heartbeating to the
RM on their own.
