Subject [jira] [Commented] (YARN-3544) AM logs link missing in the RM UI for a completed app
Date Wed, 29 Apr 2015 22:01:06 GMT

    [ https://issues.apache.org/jira/browse/YARN-3544?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14520365#comment-14520365

Zhijie Shen commented on YARN-3544:

Xuan, thanks for the patch. I've tried your patch locally, and it brought the content back
to the web UI. However, I've one concern. It seems that the link to the local log on NM is
not useful after the app is finished, because the log is not supposed to be there any longer.
So is this jira supposed to fix the regression, or ultimately provide a useful link to AM
container log? Those seem to be different goals.

> AM log links should always be present ( for both running and completed apps).
> Likewise node info is also empty. This is usually quite crucial when trying to debug
where an AM was launched and a pointer to which NM's logs to look at if the AM failed to launch.
