Subject [jira] [Commented] (YARN-2424) LCE should support non-cgroups, non-secure mode
Date Tue, 07 Apr 2015 03:17:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-2424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482505#comment-14482505

Harsh J commented on YARN-2424:
-------------------------------

[~sidharta-s] - Yes, it appears the warning was skipped in the branch-2 patch, likely by accident.
Thanks for spotting this!

Could you file a new YARN JIRA to port the warning back into branch-2?

> After YARN-1253, LCE no longer works for non-secure, non-cgroup scenarios.  This is a
fairly serious regression, as turning on LCE prior to turning on full-blown security is a
fairly standard procedure.
