Subject [jira] [Commented] (YARN-7843) Container Localizer is failing with NPE
Date Tue, 30 Jan 2018 15:51:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7843?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16345269#comment-16345269

Rohith Sharma K S commented on YARN-7843:
-----------------------------------------

I got this issue when I was doing test by reverting YARN-2185. I saw some errors in NM something
like pattern didn't match for resources and more warning with respect to resource localization.
But I couldn't able to take either logs back up or  I didn't see full NM logs since this cluster
was launched via YARN docker containers which was configured with application timeout, got
killed since lifetime exceeded! 
I will deploy new cluster and try to reproduce this issue this week.
