Subject [jira] [Commented] (YARN-5135) ContainerRequest labels ignored -broken constructor
Date Tue, 24 May 2016 14:08:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-5135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15298219#comment-15298219

Steve Loughran commented on YARN-5135:
--------------------------------------

thanks. Though a test is also something to consider, given that there's nothing to stop the
regression re-occuring

>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: client
>    Affects Versions: 2.9.0
>            Reporter: Steve Loughran

> The backwards-compatible constructor for {{ContainerRequest}} ignores the nodeLabelExpression
parameter. As a result, you can't requests nodes with a label.
> Tagged as a blocker on the basis that it's a fundamental regression. Sorry.
> This surfaces in the slider test {{TestRoleHistoryOutstandingRequestTracker}}; YARN itself
needs a unit test here to verify the regression is fixed, and that it doesn't come back.
