Subject [jira] [Commented] (YARN-4589) Diagnostics for localization timeouts is lacking
Date Tue, 19 Jan 2016 18:05:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-4589?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15107096#comment-15107096

Chang Li commented on YARN-4589:
--------------------------------

[~jlowe] please help review the latest patch.
Latest implementation add a new container external state localizing, and in each nodeheartbeat
to rm, RMNode maintains and updates states of its container. When RMAppattempt timeout it
queries from RMNode about its container state. The implementation also considers backward
compatibility

> 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.
