Andrew Ferguson updated MAPREDUCE-4334:
---------------------------------------
Attachment: MAPREDUCE-4334-v1.patch
Following a suggestion from Todd Lipcon, this version uses Cgroups to simply
balance the CPU resources consumed by containers (they are still used for
memory limits). This allows us to fairly share CPU resources today, while
MAPREDUCE-4327 is still being worked on.
> Add support for CPU isolation/monitoring of containers
