[jira] [Updated] (MAPREDUCE-4334) Add support for CPU isolation/monitoring of containers

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4334?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Ferguson updated MAPREDUCE-4334:
---------------------------------------

    Attachment: MAPREDUCE-4334-pre1.patch

This is a preliminary patch to add support for using cgroups to do resource isolation and enforcement. It requires MAPREDUCE-4351, which provides pluggable ContainersMonitors.

This patch currently assumes that the memory cgroups controller is mounted at "/cgroups/mem" and that a "/cgroups/mem/hadoop-yarn" group exists which is writable by the Hadoop user (this is configurable by yarn-site.xml). I will fix these assumptions shortly, but wanted to get the preliminary patch out for discussion.


thanks!

> Once we get in MAPREDUCE-4327, it will be important to actually enforce limits on CPU consumption of containers. 
> Several options spring to mind:
> # taskset (RHEL5+)
> # cgroups (RHEL6+)
