Vinod Kumar Vavilapalli commented on YARN-1856: ----------------------------------------------- When we use cgroups, we don't need (and want) explicit monitoring. Cgroups are going to constrain memory usage of the process (and the tree) if the right values are set when creating the group. There were some discussions on YARN-3 and related JIRAs related to this. In essence, the ContainersMonitor is really a monitor to be used only when such a OS feature is not available to properly constrain memory-usage. > cgroups based memory monitoring for containers > ---------------------------------------------- > > Key: YARN-1856 > URL: https://issues.apache.org/jira/browse/YARN-1856 > Project: Hadoop YARN > Issue Type: Sub-task > Components: nodemanager > Affects Versions: 2.3.0 > Reporter: Karthik Kambatla > Assignee: Karthik Kambatla > -- This message was sent by Atlassian JIRA (v6.2#6252)
