Owen O'Malley commented on YARN-2424: ------------------------------------- This is a pretty clear case of trying to fix the breakage from YARN-1253. Yahoo ran clusters for a year with LCE before security was turned on and got significant value from that. The largest being that it prevents "killall -9 java" type mistakes on the part of users. (Yes that did actually happen.) > LCE should support non-cgroups, non-secure mode > ----------------------------------------------- > > Key: YARN-2424 > URL: https://issues.apache.org/jira/browse/YARN-2424 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 2.3.0, 2.4.0, 2.5.0, 2.4.1 > Reporter: Allen Wittenauer > Priority: Blocker > Attachments: YARN-2424.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
