Varun Vasudev updated YARN-2440:
--------------------------------
Attachment: apache-yarn-2440.2.patch
Uploaded a new patch. It adds two new parameters to the YARN configuration.
1. yarn.nodemanager.containers-cpu-cores - can be set to the number of cores
admins want YARN containers to use.
2. yarn.nodemanager.containers-cpu-percentage - can be set a percentage of
overall CPU that admins want YARN containers to use.
By default, we use all cores.
I've also updated the description of yarn.nodemanager.resource.cpu-vcores to
what I think is a more accurate version.
> Cgroups should allow YARN containers to be limited to allocated cores
