Andrew Ferguson updated MAPREDUCE-4334:
---------------------------------------
Attachment: MAPREDUCE-4334-executor-v2.patch
New version of patch which hooks into the container executors to start cgroups.
This creates a pluggable "ResourceEnforcer" which is called before & after
creating a container. The ResourceEnforcer can also prefix the command to
launch the container -- this prevents us from having to modify the C code in
LinuxContainerExecutor.
This patch comes with two ResourceEnforcers: a default one, which does nothing,
and a CgroupsResourceEnforcer.
> Add support for CPU isolation/monitoring of containers
