Subject [jira] [Commented] (YARN-2424) LCE should support non-cgroups, non-secure mode
Date Tue, 19 Aug 2014 23:53:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-2424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14103063#comment-14103063
] 

Alejandro Abdelnur commented on YARN-2424:
------------------------------------------

You are saying this is proactive troubleshooting then, not meant for production? If so, then,
as I said before:

* the property has 'use-only-for-troubleshooting' in its name.
* the NM logs print a WARN at startup and on every started container stating the flag and
its un-secure nature
* the container stdout/stderr also print a WARN to alert the user of the cluster setup.

> LCE should support non-cgroups, non-secure mode

>          Issue Type: Bug

>    Affects Versions: 2.3.0, 2.4.0, 2.5.0, 2.4.1

> 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.
