[jira] [Commented] (YARN-1944) Application Container commands fail to stop when application is killed

["Billie Rinaldi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-1944?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13969861#comment-13969861 ] 

Billie Rinaldi commented on YARN-1944:
--------------------------------------

Having looked into YARN-1922 recently, I wouldn't have expected to see processes staying around after containers were killed by Yarn.  What OS are you using?  Does the "setsid" command exist?  I think Yarn only kills the entire process group if setsid is available.

>          Issue Type: Bug

> When launching Yarn Application with an infinite command (e.g., ping google.com), Application Container stops while command(s) continues to run.
> For example:
> Command: ping google.com; 4 containers
> Submit app:
> {code}
> ApplicationId appId = this.yarnClient.submitApplication(appContext);
> {code}
> Kill app:
> {code}
> this.yarnClient.killApplication(appId);
> {code}
> Produces the following output:
> {code}
> 13:10:22,017 ERROR IPC Server handler 48 on 8035 resourcemanager.ApplicationMasterService:328 - Application doesn't exist in cache appattempt_1397581697363_0002_000001
> {code}
> Why is it telling me that it doesn't exist when I am using the same AppId that was returned by the YarnClient?
> Also, I can see that after the kill the actual application containers stopped:
> {code}
