Subject [jira] [Commented] (YARN-4589) Diagnostics for localization timeouts is lacking
Date Fri, 15 Jan 2016 16:46:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-4589?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15102051#comment-15102051

Jason Lowe commented on YARN-4589:
----------------------------------

Thanks for the patch, Chang!  I haven't looked at the patch in detail, but I see makes significant
changes to both YARN and MapReduce.  Please split the MapReduce portion out into a separate
JIRA.  It will help reduce the size of this patch to make it more focused and easier to review,
and backwards compatibility dictates that this patch cannot require the MapReduce-side changes.

> When a container takes too long to localize it manifests as a timeout, and there's no
indication that localization was the issue. We need diagnostics for timeouts to indicate the
container was still localizing when the timeout occurred.
