Subject [jira] [Commented] (YARN-2630) TestDistributedShell#testDSRestartWithPreviousRunningContainers fails
Date Wed, 01 Oct 2014 05:50:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14154395#comment-14154395

Jian He commented on YARN-2630:

bq. Is it correct to only notify NM when keepContainersAcrossApplicationAttempts is set? 
I added this check because in work-preserving AM restart, 2nd AM needs to know about the previous
AM's finished containers. So we should not pre-maturely make NM remove the containers, in
case RM restarted.

> The problem is that after YARN-1372, in work-preserving AM restart, the re-launched AM
will also receive previously failed AM container. But DistributedShell logic is not expecting
this extra completed container.
