Subject [jira] [Commented] (YARN-561) Nodemanager should set some key information into the environment of every container that it launches.
Date Tue, 23 Apr 2013 21:47:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13639673#comment-13639673

Vinod Kumar Vavilapalli commented on YARN-561:
----------------------------------------------

Xuan, we need a separate patch for branch-2, the trunk patch isn't applying. Can you please
generate one, run all the tests on branch-2 applying that patch? We can't do that on Jenkins,
as it isn't built for running tests on branches. Tx.

> Information such as containerId, nodemanager hostname, nodemanager port is not set in
the environment when any container is launched. 
> For an AM, the RM does all of this for it but for a container launched by an application,
all of the above need to be set by the ApplicationMaster. 
> At the minimum, container id would be a useful piece of information. If the container
wishes to talk to its local NM, the nodemanager related information would also come in handy.
