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!
